How an Automated Sample Prep Workstation Works

by Questron Technologies
Problem: With unrelenting need for accurate sample analysis at lower and lower detection limits, there is pressure on modern laboratories for sample prep instruments that can provide automated, accurate reagent additions to previously prepared liquid samples or for preparing several aliquots of these samples with multiple dilution factors. The catch-all phrase that identifies these devices is “liquid handling systems” and they perform absolutely essential tasks that have a direct and large effect on the ultimate measurement accuracy of both inorganic and organic sample analysis.

How Safe, Efficient, and Productive Block Digestion Works

Problem: Bringing samples into a mineralized state is usually the first step for performing accurate inorganic analysis, aka metals trace analysis. This conversion of a usually non-homogenous insoluble mixture into a representative, homogenous aqueous solution using heat and acids is usually a prerequisite for further analysis work with spectroscopic or chromatographic techniques.
