Introduction:
Zero Air Generator produces a continuous flow of high purity Zero Air at the selected pressure. The modular pressure swing adsorption (PSA) unit operates with alternating pressure increase and decrease. Untreated air flows under pressure through the reaction towers containing molecular sieve adsorber. Moisture, CO, CO2, THC and other unwanted components in the air are adsorbed, leaving Zero Air Gas of required purity. During the desorption cycle, the trapped substances adsorbed are released again at low pressure and the adsorber is ready for next cycle. The residual impurity content of Zero Air Gas can be reduced to practically any value required for the user''s application. The Zero Air Generators are suitable for use in laboratories and industrial environments.

Applications:

• GC-FID, FPD, NPD, TCD, AED
• GC-MS, LC-MS-MS, ICP / NMR
• FTIR/IR, ELSD detector
• Purging, Ampule Filling
• Thermal Instruments, Turbo Evaporator (N2 Concentrator)
• All Analytical Instruments

Technical Specification:

Specifications	ATZ-01 (for 2-5 GC''s), for Imported GC
Moisture	< 2 ppm
Total Hydro Carbon	< 0.5 ppm
CO & CO2	< 2 ppm
Purity	GC/UHP grade

Product Introduction:
It''s powered by the whole sealing silent air compressor. After purification, water, oil, dust, and impurities are removed. Through pressure stable system, pure and silent air is finally produced under stable pressure.

Features:

• Improve analysis accuracy: lower cleaning requirement on the detector
• Match with GC and analytical column
• Gas Purity: the amount of hydrocarbon is less than 0.5ppm (such as methane)
• Low noise, without blockage
• Regular output flow and pressure
• QL-20 adopts oilless compressor: It''s durable in use and produces high-purity air

Application:

• Gas for flame ionization detector(FID), flame photometry detector(FPD), nitrogen phosphorous detector (NPD).
• Gas for hydrocarbon analyzer
• Atomizing gas and vent gas for Liquid Chromatography and Mass Spectrometer
• Atomic adsorption and ELSD(Evaporative Light Scattering Detector)

Zero Air Gas Generator for TOC Analyzer, Zero Air Generator for TOC Analyzer produces a continuous flow of high purity Zero Air at selected pressure. Compressor takes the air from atmosphere, the hot air is than passed through copper cooling coil. The cool air is than passed through furnace where hydrocarbons are cracked at high temperature (temp. range - 400°C to 500°C) in presence of catalyst. The furnace reaction at higher temperature breaks the hydrocarbon into CO2 & H2O. Water is drained away through 5μ & 0.01μ filter. The modular pressure swing adsorption unit operates with alternating pressure increase and decrease. Untreated air flows under pressure through the reaction towers containing molecular sieve adsorber. Moisture, CO, CO2, THC and other unwanted components in the air are adsorbed, leaving Zero Air Gas of required purity

Salient Features:

• Deliver constant pressure & flow
• Fully Automatic Programmable System
• Easy Maintenance and space saving
• Effortless and easy operation
• Improves instrument performance
• Fully regenerative, durability with PSA technology
