Sample requirements

At least 5 mg of sample should be submitted. Samples should be solid (oils will work too). No solvents must be present.

Analysis

The Perkin Elmer 2400 Series II combustion analyzer is equipped for determination of %C, %H and %N. It also has the capacity for determination of %S. Sulfur samples are run every other week. Air sensitive samples are being analyzed on Thursdays and Fridays. Samples submitted by 9.15 a.m. on Thursdays will be analyzed by 5 p.m. on Fridays. If a sample will react in air within 10 minutes, it must be submitted as an air sensitive sample.
