When considering that the range of compounds that might be subject to chromatography goes from highly volatile species with molecular weights of tens of Daltons, to proteins with molecular weights of hundreds of thousands of Daltons, maybe it isn’t so surprising that there are a variety of separation techniques required.
Tip #82: How to create a Custom Field in Empower Welcome back to Get Empowered! In the last Empower tip-of-the-week post for Empower CDS Software, we learned about using the Result Audit Viewer to understand the… Read more >
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.
