zNose Series
The Model 4300 zNose is a fully portable GC/SAW that can detect and analyze all types of vapors and identify traces of organic and chemical compounds quickly and accurately. It is designed with an internal helium cylinder (refillable), and can adapt to use disposable helium cylinders. The lithium ion battery is rechargeable, typically lasting 6 hours. The 4300 and 7100 models provide more quantitative results than the 4600, but require an external computer. The 7100 model is not portable.
