Agilent Technologies Flowmeters

Agilent manufactures the largest selection of flowmeters for chromatography. They have developed flowmeters for measuring capillary column flows, calibrating air pumps and flow controllers, and verifying instrument gas flows.

Choose from the following flometers:

• Agilent Technologies High Precision Gas Flowmeter
• ADM Flowmeters
• Gas Leak Detector

Agilent's Precision Gas Flow Meter is the ultimate gas flow meter for chromatography applications. This hand-held flow meter incorporates industry leading performance and features a highly accurate and reliable package. The inherent stability of the rugged, solid state components allows us to provide the longest calibration interval on the market, all traceable to NIST standards.

• Highly accurate and reliable measurement of common carrier and fuel gases used in GC, including nitrogen, air, carbon dioxide, hydrogen, helium, and argon/methane
• Two year guaranteed calibration period traceable to NIST standards
• Measures flow based on gas viscosity properties with an accuracy of ± 0.8% of reading + 0.2% of full scale
• Flow rate range from 5-500 mL/min
• Displays mass flow, volumetric flow, temperature, and pressure readings simultaneously
• Can be plumbed inline

ADM flowmeters are ideal for measuring gas streams with a changing gas composition. For example, if you measure the gas flow from a digestion system, concentration changes in methane, carbon dioxide, and oxygen will not affect accuracy. All ADM flowmeters are battery powered and field portable. Agilent calibrates each instrument to 5-point, NIST-traceable standards to ensure the highest available accuracy. The ADM family measures flow volumetrically, so you don’t have to make any adjustments when changing from one gas to another.

ADM 1000

• Accuracy ± 3%
• Operating temperature range—0 to 45ºC for the instrument, -70 to 135ºC for the tubing.
• Calibration—traceable to NIST primary standards
• Real time, split ratio measurement
• CE mark certified
• Measures flow rates from 0.5 to 1000 mL/min
• Split ratios—compare the ratio from one gas measurements to another (i.e., injection port split ratios)

ADM 2000

in addition to the ADM 1000

• Mass flow measurements—measure flow rate, independent of atmospheric pressure and temperature (calculated)
• Data output through RS-232 port
• 9V battery and AC power adapter (120 or 220 VAC)

Gas leaks can cause detector noise and baseline instability, shorten column life and waste expensive carrier gas. Liquid leak detectors, although inexpensive, can contaminate your system. Agilent's G3388A electronic leak detector is an easy way to quickly identify leaks in your system and prevent system downtime.
