For fuel chromatography (GC) and different analytical instrument applications, the required gasoline purity, outlet pressure, drift rate, and moisture degree must be matched to the instrument manufacturer's specifications. Contact QiweiLab to talk about your instrument configuration and verify whether or not the QW-KQ-19 or every other fuel grant configuration is suitable.
product key technologies
Introduction
A laboratory air generator is an industrial device that uses a compressor as its core component to deliver a stable air supply by compressing, filtering, and drying ambient air. As an automated air supply unit integrating air compression, purification, and drying functions, it has gradually become standard equipment in laboratories and industrial sites.
Its core function is to provide clean, continuous compressed air for precision instruments such as gas chromatographs (GC), mass spectrometers (MS), and atomic absorption spectrometers (AAS). It is also widely used in industrial production, medical equipment, environmental protection, and other fields.
The basic structure includes a compressor, air storage tank, filters (activated carbon/molecular sieve), drying chamber (monitored by color-changing silica gel), and a control system.
Feature
1. It can replace traditional high-pressure air cylinders and realize instrumentalization in laboratories.
2. Equipped with a large-capacity stainless steel air storage tank.
3. Simple operation: gas generation starts just by turning on the power switch; it supports continuous and intermittent operation.
4. Adopts two-stage voltage stabilization for higher pressure stabilization accuracy.
5. Built-in overpressure protection function.
6. Equipped with an automatic drainage device for safer and more convenient use.
7. Designed with atmospheric pressure start function to extend service life.
8. The compressor is provided with overload and overheat automatic power-off protection; it will cut off power automatically when the compressor shell temperature exceeds 80℃.

Stable Air Flow and Pressure for Laboratory Use
A laboratory air generator have to be chosen in accordance to the float and strain requirements of the linked instrument. The QW-KQ-19 is presently listed with an exhaust waft price of forty L/min and a two-stage stress stabilization design.
The genuine outlet stress range, strain stability, and accessible go with the flow beneath working stress must be established earlier than connecting the generator to a GC system. A nominal go with the flow ranking on my own does now not set up whether or not the unit can meet a unique instrument's gasoline furnish requirements.
For utility matching, please supply the required waft rate, working pressure, variety of linked instruments, and meant running conditions.
Safety Operation Specification
1. Environmental requirements: The equipment should be placed in a dry, ventilated and dust-free environment to avoid high temperature or humidity.
2. Operating habits: avoid frequent switching, reduce the impact on the equipment; empty the electrolyte for a long time.
3. Emergency treatment: found air leakage, odor or abnormal noise, immediately power off and contact the professional maintenance.
Maintenance
● Regular cleaning: Regular cleaning of the various components of the air generator, including filters, pressure stabilizing system, etc., to maintain its good working condition.
● Check fasteners: Always check and tighten all connecting parts to ensure that there is no looseness to ensure the tightness of the system.
● Pay attention to the use of the environment: Ensure that the air generator is in a clean, dry and well ventilated environment to prevent faults caused by moisture or pollution.
● Follow the operating procedures: When operating the air generator, be sure to follow the relevant operating procedures and manuals to avoid misoperation or improper use.
● Regular calibration: In order to ensure the purity and accuracy of the output air, it is recommended to calibrate and test the air generator regularly.
FAQ
1.What is a laboratory air generator used for?
A laboratory air generator materials compressed air for laboratory and analytical applications. The required fuel high-quality relies upon on the linked instrument and its meant use.
2.Can a laboratory air generator be used as a zero air generator for GC?
Not each laboratory air generator meets zero-air specifications. GC functions may additionally require managed hydrocarbon content, moisture, pressure, and flow. Confirm these parameters in opposition to the instrument manufacturer's necessities earlier than deciding on a model.
3.What does a whole hydrocarbon stage beneath 0.1 ppm mean?
It suggests that the measured complete hydrocarbon attention in the output gasoline is beneath 0.1 components per million underneath the mentioned take a look at conditions. This declare need to be supported by means of an terrific take a look at file and have to no longer be assumed for each air generator.
4.What output strain and glide charge are required for GC?
The required strain and waft rely on the instrument model, detector type, and variety of related instruments. Check the instrument documentation and verify the generator's on hand float at the required working pressure.
5.Why are filtration and air drying important?
Filtration and drying assist manage particles and moisture in compressed air. The required filtration grade and outlet dew factor rely on the software and the linked equipment.
6.How can I request a appropriate GC gasoline furnish configuration?
Send QiweiLab your instrument model, required drift rate, working pressure, gasoline best specifications, and volume requirements. Our group can evaluation the handy product records and assist determine configuration compatibility.
