We answer a question as a follow-up to Tip #74 on using Empower’s System Suitability option to calculate the ratio of peak to valley height when there’s a valley between the chromatographic peaks; What about calculating valley height when there are two fused peaks?
Lots of questions about calculating impurities in Empower Software! Here’s another answer to a reader who inquired: How do you quantitate impurities against the main component? We’re happy to show how…
We answer another reader’s question about using Empower Software: How do you summarize specified and unspecified impurities in a sample and quantitate them against the main component?
We answer a reader’s question about using Empower Software: How do you calculate impurity response when there are two APIs in the sample?
We answer another reader’s question: Why is the retention time of my peak slightly different than the retention time of the UV apex spectrum for the peak?
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?
#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.
