Long pathlength Gas Cell/Short pathlength Gas Cell
Gas measurement Accessory

Long path gas cells - used to measure low-concentration gas samples.

Short path gas cell  - used to measure high-concentration gas samples (gas samples with a concentration usually higher than 1% by weight).

Long path gas cells -
- Fixed path length is available from 2.4m to 30m
- BaF2, CaF2, KBr, NaCl, ZnSe window materials are available
- The cells material includes metal, stainless steel, glass..etc

Short path gas cell -
- 100mm and 50mm gas cells are available.
- BaF2, CaF2, KBr, NaCl, ZnSe window materials are available

Long path gas cells -
1. Can measure gas concentration to ppb level
2. Choice of fixed or variable path length
3. Heating type can reach 200℃
4. Possess a purge optical system

Short path gas cell -
1. Used to detect high-concentration gas samples
2. High sensitivity
3. Use sliding installation
4. Possess purge optical system

Long path gas cells -
Special applications: automobile exhaust emission, production line gas analysis, factory exhaust emission

Short path gas cell -
Applicable to all FTIR
