Simplify Multipoint Calibration of Your GC

Product Announcement from Environics, Inc.

Our systems can produce gas concentrations from percent to ppb levels at the required flow rates for single or multi-point calibration.  In all cases, Environics mixers allow you to use less expensive single-gas cylinders or bulk tanks in place of a high number of expensive blended cylinders.

Flexibility:  Environics’ systems automatically blend and dilute gases to generate precise gas mixes.  The Series 2014 VOC Gas Dilution System can be used to dynamically produce parts per billion level standards from parts per million level cylinder gases, while the Series 4040 automatically generates precise gas standards and is operated through any laboratory computer.  Each component concentration can be independently varied in response to your commands.  Customization of our systems is always possible.

Accuracy: Our gas mixing technology is based on very precise control of thermal mass flow controllers. Normally, thermal mass flow controllers offer an accuracy +/- 1% of full-scale flow. However, when combined with Environics computerization and calibration, this accuracy specification is improved to +/- 1% of setpoint. The Full-scale error vs. Setpoint error document shows the 10x improvement in accuracy of a thermal mass flow controller when using Environics controlling technology.

Repeatability:  Our systems have a repeatability of +/-0.05% of full scale.

NEW! The ZAG now includes with dual pressure regulation for enhanced performance. 

Our Zero Air Generators (ZAG) are capable of continuous delivery of up to 20 standard liters per minute (SLPM), 30 pounds per square inch (PSI) of dry, contaminant-free air.  The ZAG is a powerful stand-alone unit, so there is no need for you to worry about an external compressed air supply.  The air is a perfect method for generating zero reference calibration gas, ultra-pure combustion air for flame ionization detector, service air for pneumatically operated valves, hydrocarbon free chromatography use and general laboratory use. 

Oxygen Clean:  We offer systems cleaned for oxygen service, and highly recommend cleaning of all components for systems that will be subjected to oxygen levels above 25%.

Tubing and Seals Choices:  We offer a variety of tubing and seal options to best fit your particular situation.  Our team will help guide you to the proper material, which may include stainless steel, Teflon, Hastelloy or Monel tubing and Viton®, Kalrez®, Buna-N, Neoprene or Metal seals.

Custom Systems: We have thousands of systems in the field and have developed an extensive library of applications and solutions to meet our customers' needs.  Examples of custom systems currently in the field can be seen below.  Other optional features, such as audible/visual alarms, humidification or ozone generation, are available to best suit your needs.  Contact us for more information.
