MEMILIH LABORATORIUM

Ada banyak faktor yang perlu dipertimbangkan dan banyak item yang harus ditinjau ke

laboratorium lingkungan untuk proyek Anda. Pertama dan yang terpenting, memahami b

laboratorium menampilkan NELA !atau TN"# logo, tidak menjamin kualitas atau kesesuaian

proyek Anda. Laboratorium harus mampu menunjukkan kemampuan untuk menghasilka

diandalkan yang memenuhi standar nasional dan kriteria proyek Anda.

Tugas mencari laboratorium yang tepat dapat menantang, terutama jika Anda tidak terbiasa

teknis, persyaratan peraturan, dan kimia pada umumnya.

$aya telah melihat hal ini banyak sekali ketika pilihan laboratorium dilakukan dalam tergesa%gesanalisis menjadi kriteria utama. &anajer proyek atau siapa pun yang mencari dukungan analisaharus menyadari bahwa menghemat biaya kedepannya justru bisa berarti biaya yang lebih tingdata yang tidak dapat digunakan. $kenario yang lebih buruk adalah jika pengguna data tidak mdata dan data tersebut akan digunakan untuk beberapa proyek mahal atau penting
