Automatic samplerAS

is an automatic sampler to inject liquid samples in DANI

Automatic sampler

AS

GC

Sample trays and syringe needles are

positioned away from all heated surfaces. This configuration prevents volatile

solvent evaporation and degradation of thermally sensitive

samples.

MASTER AS – Sample Integrity

Why an Automatic Sampler?

The automatic sampler assures:

– identical movements– constant amount of solvent, air, internal

standard and sample into the syringe– constant speed of the plunger and time

intervals

MASTER AS – Why an Automatic Sampler

It offers repeatability and accuracy not available by manual injection.By manual injection, RSD% is never lower than 3%, ever with cold injection.

MASTER AS – Why an Automatic Sampler

Providing innovative sampling solutions, the DANI AS maximizes

laboratory productivity, mixing robotic technology with advanced three-dimensional

space movements (X-Y-Z)

MASTER AS – 3D Space Movements

AS provides unprecedented automation and greater flexibility in sample capacity.

It provides maximum sample throughput with a standard 160 sample tray for 2mL vials or 65 sample tray for 10mL vials.

MASTER AS – Syringe

The sample volumes, from 0.1 to 500 µl, are measured with great accuracy and precision.

This guarantees repeatability and linearity of the quantitative data.
