ELEMENTAL ANALYSIS SERVICE

INTRODUCTION

The goal of this service is the simultaneous determination of the percentage of carbon (C), hydrogen (H), nitrogen (N), and sulfur (S) on a given sample, being either in liquid or in solid state. 

This technique is based on the complete combustion of the sample, under optimal conditions (1000-1300 ºC, O₂ atmosphere), in order to transform the target elements (C, H, N, S) into CO₂, H₂O, N₂ and SO₂, respectively.

These gases, after frontal crhomatographic separation, are detected, quantified, and processed taking onto account the weight of the sample and the calibration performed with a standard reference. This process finally affords the percentage of each element in the problem sample.
