Trace Level Total Sulphur/Nitrogen Analysis in Wax Samples

TSHR International have developed a new application note for the simultaneous analysis of Total Sulfur and Nitrogen in wax samples based on high temperature combustion with UV-Fluorescence and chemiluminescence detection in compliance with ASTM D5453 and D4629 methods.

The analysis of wax samples with the TSHR TN/TS 7000 model instrument and liquid autosampler equipped with heated tray and 20 uL sample volume, provides customers significant savings on analysis time and less risk of potential contamination issues.

The obtained RSD’s based on 4 replicates are for nitrogen lower than 4% and for sulphur lower than 2% for the set of wax samples.

The application with heated tray of the HR 7100 sampler, results into an excellent performance and no limitations towards sample pickup or introduction. The Athena software for analyser operation, with method templates, generate also the calibration used for determine the total sulphur and nitrogen content in the samples.

The used TSHR liquids autosampler, HR 7100 model, with maximum 121 positions for 2 mL vials and equipped with heated tray at 60 ^oC drives the productivity and repeatability of the data as presented in the application note.
