The Model 4080 is designed to detect hydrocarbons (C1-C9+) which may not absorb in the UV region)
4000 Series Overview:
All 4000 series units employ the same basic architecture and electronics; however, each analyzer has additional features:
4020 Total Hydrocarbon Analyzer | Uses FID to measure total hydrocarbons in ppm in a sample gas stream |
4030 Total Hydrocarbon Analyzer | Basic 4020 with sample system at a higher temperature for heated applications Avoids condensation of the sample |
4040 Methane / Non-Methane | Basic 4020, plus temperature-controlled sampling system with GC column to give accurate readings of both methane and non-methane hydrocarbons in a gas stream |
4060 Benzene Analyzer | Same as 4040, but used to measure ppb levels of benzene instead of methane/non-methane |
4080 Total Hydrocarbon Analyzer | Basic 4020 with sample system including stripper to measure total hydrocarbons in an aqueous sample |
• Designed to detect hydrocarbons (C1 – C9+) which may not absorb in UV region
• Temperature controlled stripper system effectively strips hydrocarbons from water by cross flowing N2 over the packed stripper column.
• Includes Drier Assembly to ensure a dry sample gas is delivered to the analyzer
• Model 4020 THC analyzer to measure trace THC in gas phase
• Standard ranges : 0-10, 0-100, 0-1,000 ppm hydrocarbons (methane equivalent)
• Output: 0-1 VDC and 4-20 mADC, Isolated current output
• Fuel: Mixture of 40% hydrogen / 60% nitrogen
• Two user configurable alarm points and corresponding relays
• Electronic flame guard circuit and fuel shut-off solenoid valve
• Dual-sided, free standing rack with Stripper Sample System mounted on the backside and Model 4020 NEMA-4 enclosure provided on front
• Optional configurations with sunshade and all components on front panel are available
