SGC（Sensor Gas Chromatograph）

SGC（Sensor Gas Chromatograph）

Nissha FIS SGC（Sensor Gas Chromatograph） realizes quick gas separation and super gas sensitivity by using Nissha FIS original short column and Nissha FIS semiconductor gas sensor.

Application fields

SGC can be used to detect very small gas in various fields.

  • Factory environment measurement

    Environmental measurement inside and outside a factory, malodor processing ability check, etc.

  • Garbage odor control

    Garbage released odor control, odor prevention in the neighborhood, etc.

  • Deodorizer performance evaluation

    Performance and deterioration evaluation for deodorizers, etc.

  • Food freshness check/food production quality control

    Quality control and freshness check in food processing process, etc.

  • Very small amount gas analysis in R&D

    Very small amount gas analysis in R&D of environmental, medical, and micro-organism fields

Feature

Super sensitive measurement of quite small amounts of gas

Since extremely high sensitive semiconductor gas sensor is used as a detector, ppb (parts per billion) level measurement can be realized.

Easy operation/short time measurement

Simply injecting sample gas starts measurement automatically. The measurement is completed in 4 or 8 minutes.

No carrier gas cylinder required

SGC uses ambient air as carrier gas so that high pressure gas cylinder is not necessary. Note: Some models need the cylinder.

Small size/light weight/Portable

Our original technology including a short length column has realized a small size (B4 size) and light weight (5.5kg) unit with excellent portability that does not require a limited installation site.

Real time data viewing with attached software

SGC is supplied with a standard software displaying the real-time measurement results on PC. This software has various features such as chromatography chart, gas concentration display, and continuous measurement (optional) display.

*Please supply your own PC.

sgc_pic01*PC is not included.

Customizable

SGC can be customized to meet your demand.

Examples:

  • For use with high purity air cylinder as carrier gas, if the ambient air around SGC is polluted, etc.
  • Automatic gas injection and continuous measurement (continuous monitoring is possible by automatic sampling function)
  • For the measurement of other gas than currently available gases

Continuous measurement (automatic gas injector) ＊Optional feature

Automatic continuous measurement is possible by setting total measurement duration time or total measurement times.
