Chromatography is by nature adiscontinuous process
Continous Annular Chromatography(CAC) offers the possibility ofcontinuously feeding the columnwith a mixture at a fixed point
The solutes migrate and separatewhile the solid phase rotates Thedifferent analytes will then exit thecolumn at a point that can bedetermined from their retention time
and the column rotation speed

Process Analytical Technology applied to DSP
The PAT guidelines proposed by the FDA aim at a bettercontrol and understanding of biotechnology processes
In the case of DSP this can be achieved by on-line
monitoring of target substances and main contaminants Shorter analytical response times can certainly help
improve the productivity of purification trains be it onlyby a reduction of down times
Some examples have been found in the literature thatillustrate the above considerations drying of APIs real-time monitoring of crystallization breakthrough of targetmolecule out of a Protein A adsorption step

Smart polymers and affinity precipitation
Precipitation is simple low-cost and easily scalable
Many precipitating agents are known and characterized
Precipitation selectivity is usually low but can beimproved by grafting affinity ligands on polymers
Smart (responsive) polymers undergo precipitation uponslight modifications of temperature or pH
Applications include biocatalysis isolation of proteins hellip

Conclusion and outlook
DSP has to catch up with the dramatic increase inproductivity of modern biopharmaceutical processes
A lot can certainly be done by following a PAT approach toDSP (shorter response times optimal use of capacity)
Use of disposable separation components can probablyhelp reduce cycle time
New techniques such as improved stationary phasesmonolith amp membrane chromatography have potential
Revamping of neglected low-costhigh capacitytechniques such as precipitation look promising
The industry is very conservative and evolution is slow butunavoidable

Process Analytical Technology applied to DSP
The PAT guidelines proposed by the FDA aim at a bettercontrol and understanding of biotechnology processes
In the case of DSP this can be achieved by on-line
monitoring of target substances and main contaminants Shorter analytical response times can certainly help
improve the productivity of purification trains be it onlyby a reduction of down times
Some examples have been found in the literature thatillustrate the above considerations drying of APIs real-time monitoring of crystallization breakthrough of targetmolecule out of a Protein A adsorption step

Conclusion and outlook
DSP has to catch up with the dramatic increase inproductivity of modern biopharmaceutical processes
A lot can certainly be done by following a PAT approach toDSP (shorter response times optimal use of capacity)
Use of disposable separation components can probablyhelp reduce cycle time
New techniques such as improved stationary phasesmonolith amp membrane chromatography have potential
Revamping of neglected low-costhigh capacitytechniques such as precipitation look promising
The industry is very conservative and evolution is slow butunavoidable

Smart polymers and affinity precipitation
Precipitation is simple low-cost and easily scalable
Many precipitating agents are known and characterized
Precipitation selectivity is usually low but can beimproved by grafting affinity ligands on polymers
Smart (responsive) polymers undergo precipitation uponslight modifications of temperature or pH

Conclusion and outlook
DSP has to catch up with the dramatic increase inproductivity of modern biopharmaceutical processes
A lot can certainly be done by following a PAT approach toDSP (shorter response times optimal use of capacity)
Use of disposable separation components can probablyhelp reduce cycle time
New techniques such as improved stationary phasesmonolith amp membrane chromatography have potential
Revamping of neglected low-costhigh capacitytechniques such as precipitation look promising
The industry is very conservative and evolution is slow butunavoidable

Process Analytical Technology applied to DSP
The PAT guidelines proposed by the FDA aim at a bettercontrol and understanding of biotechnology processes
In the case of DSP this can be achieved by on-line
monitoring of target substances and main contaminants Shorter analytical response times can certainly help
improve the productivity of purification trains be it onlyby a reduction of down times
Some examples have been found in the literature thatillustrate the above considerations drying of APIs real-time monitoring of crystallization breakthrough of targetmolecule out of a Protein A adsorption step

Conclusion and outlook
DSP has to catch up with the dramatic increase inproductivity of modern biopharmaceutical processes
A lot can certainly be done by following a PAT approach toDSP (shorter response times optimal use of capacity)
Use of disposable separation components can probablyhelp reduce cycle time
New techniques such as improved stationary phasesmonolith amp membrane chromatography have potential
Revamping of neglected low-costhigh capacitytechniques such as precipitation look promising
The industry is very conservative and evolution is slow butunavoidable

Process Analytical Technology applied to DSP
The PAT guidelines proposed by the FDA aim at a bettercontrol and understanding of biotechnology processes
In the case of DSP this can be achieved by on-line
monitoring of target substances and main contaminants Shorter analytical response times can certainly help
improve the productivity of purification trains be it onlyby a reduction of down times
Some examples have been found in the literature thatillustrate the above considerations drying of APIs real-time monitoring of crystallization breakthrough of targetmolecule out of a Protein A adsorption step

Conclusion and outlook
DSP has to catch up with the dramatic increase inproductivity of modern biopharmaceutical processes
A lot can certainly be done by following a PAT approach toDSP (shorter response times optimal use of capacity)
Use of disposable separation components can probablyhelp reduce cycle time
New techniques such as improved stationary phasesmonolith amp membrane chromatography have potential
Revamping of neglected low-costhigh capacitytechniques such as precipitation look promising
The industry is very conservative and evolution is slow butunavoidable

In the case of DSP this can be achieved by on-line

Conclusion and outlook
DSP has to catch up with the dramatic increase inproductivity of modern biopharmaceutical processes
A lot can certainly be done by following a PAT approach toDSP (shorter response times optimal use of capacity)
Use of disposable separation components can probablyhelp reduce cycle time
New techniques such as improved stationary phasesmonolith amp membrane chromatography have potential
Revamping of neglected low-costhigh capacitytechniques such as precipitation look promising
The industry is very conservative and evolution is slow butunavoidable

Conclusion and outlook
DSP has to catch up with the dramatic increase inproductivity of modern biopharmaceutical processes
A lot can certainly be done by following a PAT approach toDSP (shorter response times optimal use of capacity)
Use of disposable separation components can probablyhelp reduce cycle time
New techniques such as improved stationary phasesmonolith amp membrane chromatography have potential
Revamping of neglected low-costhigh capacitytechniques such as precipitation look promising
The industry is very conservative and evolution is slow butunavoidable

Conclusion and outlook
DSP has to catch up with the dramatic increase inproductivity of modern biopharmaceutical processes
A lot can certainly be done by following a PAT approach toDSP (shorter response times optimal use of capacity)
Use of disposable separation components can probablyhelp reduce cycle time
New techniques such as improved stationary phasesmonolith amp membrane chromatography have potential
Revamping of neglected low-costhigh capacitytechniques such as precipitation look promising
The industry is very conservative and evolution is slow butunavoidable

Conclusion and outlook
DSP has to catch up with the dramatic increase inproductivity of modern biopharmaceutical processes
A lot can certainly be done by following a PAT approach toDSP (shorter response times optimal use of capacity)
Use of disposable separation components can probablyhelp reduce cycle time
New techniques such as improved stationary phasesmonolith amp membrane chromatography have potential
Revamping of neglected low-costhigh capacitytechniques such as precipitation look promising
The industry is very conservative and evolution is slow butunavoidable

Conclusion and outlook
DSP has to catch up with the dramatic increase inproductivity of modern biopharmaceutical processes
A lot can certainly be done by following a PAT approach toDSP (shorter response times optimal use of capacity)
Use of disposable separation components can probablyhelp reduce cycle time
New techniques such as improved stationary phasesmonolith amp membrane chromatography have potential
Revamping of neglected low-costhigh capacitytechniques such as precipitation look promising
The industry is very conservative and evolution is slow butunavoidable

Conclusion and outlook
DSP has to catch up with the dramatic increase inproductivity of modern biopharmaceutical processes
A lot can certainly be done by following a PAT approach toDSP (shorter response times optimal use of capacity)
Use of disposable separation components can probablyhelp reduce cycle time
New techniques such as improved stationary phasesmonolith amp membrane chromatography have potential
Revamping of neglected low-costhigh capacitytechniques such as precipitation look promising
The industry is very conservative and evolution is slow butunavoidable

03092010 Trends and trend setters in DSP 32
(X) Continuous Annular Chromatography
Chromatography is by nature adiscontinuous process
Continous Annular Chromatography(CAC) offers the possibility ofcontinuously feeding the columnwith a mixture at a fixed point
The solutes migrate and separatewhile the solid phase rotates Thedifferent analytes will then exit thecolumn at a point that can bedetermined from their retention time
and the column rotation speed
Prior Engineering is one of the onlysuppliers for such systems

Conclusion and outlook
DSP has to catch up with the dramatic increase inproductivity of modern biopharmaceutical processes
A lot can certainly be done by following a PAT approach toDSP (shorter response times optimal use of capacity)
Use of disposable separation components can probablyhelp reduce cycle time
New techniques such as improved stationary phasesmonolith amp membrane chromatography have potential
Revamping of neglected low-costhigh capacitytechniques such as precipitation look promising
The industry is very conservative and evolution is slow butunavoidable

Process Analytical Technology applied to DSP
The PAT guidelines proposed by the FDA aim at a bettercontrol and understanding of biotechnology processes
In the case of DSP this can be achieved by on-line
monitoring of target substances and main contaminants Shorter analytical response times can certainly help
improve the productivity of purification trains be it onlyby a reduction of down times
Some examples have been found in the literature thatillustrate the above considerations drying of APIs real-time monitoring of crystallization breakthrough of targetmolecule out of a Protein A adsorption step
