摘要

Preparing analytical samples and standards for the life science laboratory, the pharmaceutical laboratory and the analytical laboratory, is typically a manual procedure that requires that solids be weighed into a volumetric flask and diluted to the mark. METTLER TOLEDO (Greifensee, Switzerland) critically reviewed the work flow and saw an opportunity to automate the sample preparation process while simultaneously reducing the impact of human variability and uncontrolled environmental factors. Specifically, it was predicted and verified that add-ing liquid by weight improves preci-sion and reduces solvent consumption by 80%. More importantly, weight/ weight sample preparation eliminates the variability of the human element.
