Does anyone use Clarus 500 for analyzing free and total glycerin in biodiesel? I am working on GC calibration. The software is Total Chrom 6.3.1 which i am learning now and feel difficult. Any help is much appreciated. Thanks.

I saw one of these in Malaysia used for this. What's the question?

Which methods are you trying to use? You should get a copy of the latest method. The EN14105 method has changed a lot in 2011. The ASTM D6584 method had incorrect calculation procedures in the first publication, but this has been corrected.

thanks. I want to know the calibration details using this chemstation, such as how to "edit component, name group, etc". But thanks for the suggestions.

ASTM D6584-the recent version. I want to know the cal details by using TOTAL CHROM Chemstation. Thanks. i assume i still need to run the five stds using old method, then add the cal results?
