(Date), 2014:Sub-Saharan gas market leader Afrox continues to maintain its competitive edge through the commissioning of the German-engineered Bruker FTIR (Fourier Transform Infrared) instrument at its ISO 9001 Gases Operation Centre Laboratory in Germiston.
This Bruker FTIR was designed specifically to analyse low level atmospheric contaminants, including; CO, COS, H2S, NOx, SOx, and will identify and quantify chemical species found in the atmosphere around us with Opus 7.0 Software and compare the spectra against an NIST library of spectra.
This makes the analytical technique extremely powerful as an investigative tool in the laboratory, and it improves the analytical tolerance of the mixtures that Afrox can analyse and supply. It complements the ‘low ppm reactive component calibration mixtures’ Afrox has been offering in stabilised cylinders, resulting in high accuracy and extended shelf life.
The instrument is equipped with an eight meter glass gas cell with gold coated mirrors to ensure that the reactive components in the sample do not react with the cell itself. The MCT detector is cooled to -196°C, a temperature where the infrared detector is at its most sensitive.
Afrox manager for special products and chemicals, Marietha Strydom states that this instrument will enable the analysis of gases to medical, pharmaceutical and aviation standards now required by Afrox customers. “It is also part of the ISO 17025 programme that Afrox has embarked on, in order to register as a calibration laboratory.”
Strydom states that the Bruker FTIR was chosen by Afrox as training and technical backup comes standard with the instrument, which adds value for Afrox and its customers. “Afrox is keeping its promise of continuous improvement, to keep abreast of market requirements, and provide top quality products and services,” she concludes.
