Available from Technical and Scientific Equipment Co (TSE), Electronic Sensor Technology's (EST) 4500 zNose portable gas chromatographer is a mobile, small footprint analyser that detects and analyses organic, biological and chemical compounds accurately and in real time.
An EST zNose portable gas chromatographer is an ultra high speed odour detector that employs a trap and helium carrier gas to separate chemicals in near real time so that pattern recognition and trace detection can be performed in seconds. Unlike trace detectors which only detect a few select compounds, this odour detector recognises odours and fragrances based upon their full chemical signature.
The 4500 zNose portable gas chromatographer has been designed with an internal helium cylinder that is refillable, and can use disposable helium cylinders. The lithium ion battery is rechargeable, typically lasting 5 hours.
Employing a trap and helium carrier gas, this portable gas chromatographer injects samples into a heated column where separation is achieved (gas chromatography). Materials sequentially exit the column and are deposited on the SAW detector. This deposition results in a change in the oscillating frequency of the resonator directly proportional to the mass.
Minimal training is required as the gas chromatographer has a built-in processor and the processor can guide the user so that compounds are automatically identified.
The zNose portable gas chromatographer uses gas chromatography calculations in a powerful manner for a variety of applications, and can adaptively learn to recognise and alert on any target odour. Such applications include chemical analysis, environmental analysis, food and beverage quality assurance, and even national security.
The portable nature of the odour detection system means that it is ideal for the manufacturing environment and applications ranging from determining fruit flavours to indentifying odours from discharges to the environment can be achieved with an array of calibrated compounds to relate to in the software library to match the operation. A benchtop model of the zNose portable gas chromatographer is also available which can achieve parts-per-trillion sensitivity and extremely fast response times.
The 4500 zNose portable gas chromatographer is a powerful odour detector that offers portable, accurate and efficient analysis, with minimal user training. The gas chromatographer is available in Australia and New Zealand from Technical and Scientific Equipment.
