We answer a reader’s question as we’re discussing how to use Empower’s System Suitability option: How can I calculate the ratio of peak height to valley height when I have a valley point between peaks?
Whether you’re in a QC lab and need to track the amount of active in each batch that ships, doing Method Development and need to track the number of injections you get out of a column, or if you are a process chemist tracking the completion of a reaction, Control Charts is a great visual tool in Empower Software. See how to use it.
72: What is the Acceptance Criteria Limits on the Limits tab in Empower Software’s System Suitability Option? What is it and when would it be used?
Q&A from a recent forensic toxicology webinar on using an ACQUITY UPLC I-Class/Xevo TQ-S micro MS system for quantifying cannabinoids in oral fluid.
Two MAM approaches for biotherapeutic analysis are being implemented today; one focused on the analysis of monoclonal antibody (mAb) subunits, and the other focused on the analysis of peptides from a protein digest (peptide mapping workflow). Both have their advantages and disadvantages. Here, we explore MAM for mAb subunit analysis.
#71: Learn how Empower CDS calculates Detector Noise and Drift using the System Suitability option.
#70. Using the System Suitability Option, learn how Empower Software calculates Baseline Noise and Drift. This can be useful if you are not in a regulated laboratory environment when you probably want to calculate Signal to Noise without the USP, EP, or JP formula.
We discuss analytical options using LC and GC with MS/MS to detect the pesticide fipronil in eggs for food safety testing.
“Assuming continuous improvement is a worthy goal, there is every reason to improve validated chromatographic methods if you’re working with the right instrument technology,” says Eric Grumbach of Waters. See what that means for developing and transferring methods for biologic drugs.
#69: Learn how Empower Software calculates Peak-to-Peak Noise for USP, EP, and JP Signal-to-Noise calculations.
