Instrument Details
Instrument/Facility Name: Headspace Gas Analyzer
Make                                   : Systech Instruments
Model                                  : GS3
Specification   :Estimation of Oxygen, Carbon dioxide and Nitrogen gas in % basis

Click to ViewThe equipment uses Zirconia, solid state ceramic, non-depleting, dual detector Infra-Red Sensors for measuring from a variety of flexible and rigid packages such as flow wrap packaging, thermoform-fill-seal trays, bulk bags, vials, plastic and foil sachets, cans and bottles. The gases measured and their range are (Oxygen 0.001% - 100%, Carbon dioxide 0.1% - 100%, Nitrogen 0.001% - 100%)

  Working Principles
Click to ViewWhen light passes through a gas stream containing carbon dioxide, the gas absorbs energy from the light at specific wavelengths. The remaining light is filtered to a wavelength specific to carbon dioxide. The amount of light remaining at the specific wavelength is measured. The amount of light absorbed is directly proportional to the amount of carbon dioxide present in the gas stream, thus enabling accurate carbon dioxide measurement. The % levels of oxygen in a gas or mixture of gases is measured with the help of zirconia cell. It is an electrochemical galvanic cell employing a high temperature ceramic sensor containing stabilised zirconium oxide. Zirconia ceramic cells only allow oxygen ions to pass through at high temperatures. With reference gas on one side and sample gas on the other, oxygen ions move from the side with the highest concentration of oxygen to that with the lowest concentration. The movement of ions generates an EMF (Electro Motive Force) which can be measured to determine the oxygen content. Nitrogen is assumed to be the balance gas and its value is computed and digitally displayed.
