Application Note ReView: AS235 – Proving the Accuracy of Automated Sample Prep
Many aspects of sample preparation are subject to variability and uncertainty, often leading to inaccurate and imprecise results. As a result, one of the most attractive advantages of using an automated sample prep instrument is their capability to provide consistent accuracy and precision to the analytical method.
This is obviously not only valuable from a health, safety, and time perspective, but it allows analysts to methodically control all experimental variables involved such as timing, temperatures, and speeds (e.g. in mixing, centrifuging and liquid handling). In fact, these are the many aspects of sample preparation which are subject to variability and uncertainty, and can lead to inaccurate and imprecise results. The consistency of automated sample preparation in performing the analytical workflow increases the robustness and accuracy and minimises analytical variability.
Therefore, this edition of Application Note ReView takes a look back at AS235 – Automated Weighing Option: Proving the Accuracy of Automated Sample Prep.
This application note showcases the capability of the weighing option, focusing specifically on liquid handling, and shows the performance benefits in terms of accuracy and precision provided by an automated sample prep instrument.
It details not only the advances in accuracy but explains the practical benefits of automating the data input into simple CSV format, saving you even more time and improving sample traceability.
The GERSTEL Multipurpose Sampler (MPS) provides this integrated weighing option. Vials are placed in the balance by the MPS then liquid samples, standards, reagents or diluents are added, weighed and registered separately. Results are automatically transferred to pre-defined Microsoft Excel tables for convenient processing. Each sample is reported in a separate line, each addition in a separate column.
This application note will showcase the capability of the weighing option proving performances in terms of accuracy and precision for automated sample preparation, focusing specifically on liquid handling.
