ANTEK has been long established as a manufacturer of elemental analysis instrumentation. The main market segment for these products has traditionally been in the petrochemical industry where their systems for nitrogen sulphur and carbon analysis have become universally known and respected.

The principle technology of oxidation of the sample by pyrolysis in oxygen rich atmosphere is well accepted. The following analysis is then by chemiluminescence for nitrogen and fluorescence for sulphur, although very low level sulphur determination can be carried out by a further reduction and a chemiluminescent measurement. This trace sulphur analysis has given the industry a fast and reliable technique, which allows monitoring to the new low levels of sulphur needed for compliance with the new regulations that are coming into force.

ANTEK have a number of patents particularly in the chemiluminescence techniques, which have brought about a dramatic increase in their use at low level determinations and have increased the scope of applications, for which these instruments can be used. Notably, this includes the pharmaceutical field where accurate, fast nitrogen determination is of great value.

This detection technique has been applied for a considerable time to the output from GC systems and latterly is being used with great success as an additional HPLC detector. It is equi-molar and unaffected by diatomic nitrogen. This rapidly expanding sector is generating a great deal of interest and consequent rapid development.
