Gravimetric Sample Preparation - Reducing Sample Size and OOS Errors

Sample preparation is an important part of an analytical workflow. However, it usually consists of tedious and time-consuming manual operations. Unfortunately, labor-intensive manual processing also constitutes a high risk of error or variability, which can lead to out-of-specification (OOS) or out-of-tolerance (OOT) results (test results which fall outside of specification or tolerance acceptance criteria). Variability in sample preparation influences the accuracy of the final results of the analysis, so it is crucial to identify and eliminate any potential sources of errors before they can have an impact on downstream results.  

Modernizing the manual sample preparation steps of an analytical workflow – by implementing automated gravimetric sample preparation, for example – has the potential to address 50% of the issues in the workflow. This offers significant potential to improve the speed and minimize the OOS errors in the process.
