Brief introduction: Instrument using purge valve technology, zero dead volume zero leakage, 2 d center cutting technology, high purity gas analysis for chromatographic column and pulse helium ionization detector (PDD) technology to the combination of high purity, high pure hydrogen and high pure nitrogen, high purity argon helium, high purity, high purity carbon dioxide and methane high purity oxygen on-line detection, etc. Samples collected quantitative ring and displacement after clean, switch sampling valve, under the drive of the carrier in the chromatographic column separation and the main component in cutting after emptying into the PDD detector in turn. Features: 1. Use special high purity gas chromatographic column technology, measuring a variety of inorganic and organic impurity components, conform to the national standard requirements; 2. The instrument has self-checking function, barely able to boot power protection function, the automatic restart function, automatic calibration and alarm functions, guarantee the system security and stability; 3. Using the membrane valve with the scavenging protection and zero leakage pipe joint design, system leakage rate < 1 * 10-8 m3. Pa. S - 1; 4. The PDD detector has a patented technology and digital output, wide range of CH4 detection limit or less 5 PPB; 5. Core part USES the international well-known brand, high reliability, long service life. Technical parameters: Detection: H2, Ar, O2, N2, CH4, CO, CO2, Kr and Xe, etc Range: CH4 (1 PPB - 1000 parts per million (PPM) Detector: pulse helium ionization detector (PDD) Detection limit: 5 PPB (CH4) Repeatability: RSD 3% or less The analysis cycle: 10 min Power supply: < 300 w, 220 v AC / 50 hz Working conditions: temperature (10 ~ 50 ℃, humidity: 10% ~ 90% RH Air requirements: carrier gas: high purity helium (99.999% or higher) Output: 4-20 ma, RS232 / RS485 and Ethernet Size: 19 "standard case, 5 u
