HS-12A
(Automatic Headspace Sampler)

HS-12A headspace sampler is a new generation of headspace sampler as newly developed by our professional engineers, which is provided with unique technical features and independent intellectual property rights. Headspace sampling can significantly reduce the process of complicated and time consuming artificial preliminary treatment to volatile compounds in liquefied and solid samples. Therefore, it is extensively used to detect volatile organisms (detection of residual solvents) in samples for petrochemical, fine chemical, food brewing and food packing materials, environmental monitoring (water in rivers and lakes), sewage , medico-legal expertise, drinking water, cosmetics, coat and paint. *  Main Points:
1. High versatility---It is available for direct connection with any homemade instrument, which is easy for operation.
2. Exquisite design---This instrument features in delicate and exquisite design, which is precise and natural in appearance.
3. High economy and durability---As manifested by persistent inspection, this instrument is stable and durable.
4. Low residual adsorption---The complete pipeline is made of inert materials to facilitate heating and heat preservation.
