Abstract

The analysis of the composition of liquefied petroleum gases is currently carried out by gas chromatography. This method is accurate, but is expensive and it is not practical for use in a low cost, field portable instrument. It has been shown that sufficient information can be obtained from the near infrared absorption spectra for the components of LPG to be distinguished. Two instruments are described: a novel device based on a number of low cost infrared light emitting diodes with a single detector, and a more conventional filter wheel based device. Experimental results indicate that an infrared system may be used to provide a robust and cost effective method of quality control of LPG products.
