Principle of Operation
The InfraRan Specific Vapor Analyzer is a single-beam infrared photometer designed specifically for
easy, on-site ambient air measurements of a particular gas or gases. The analyzer can be purchased
to measure 1 or 2 chosen gases provided they have an infrared absorption band in the infrared region
from 2.5 - 14 µm. Infrared absorption filter photometry is used to measure gas concentration.
An integral sample pump draws a gas sample into an optical transmission cell where it absorbs energy
from an infrared beam. A filter and detector convert the infrared intensity, at the wavelength selected by
the filter, to an electronic signal. An embedded microprocessor converts the reduction in beam intensity
to a concentration of the target gas and this is displayed in appropriate units (typically ppm or percent).
Fast Response
Response to 90% is less than 10 seconds with a stable maximum concentration in less than 30 seconds.
Since the air sample is continuously delivered to the cell by means of a built-in sampling pump, the analyzer
outputs real-time concentration data, allowing personnel to be alerted to potential hazards before they become serious.
Low Maintenance
The InfraRan Specific Vapor Analyzer provides a reliable , maintenanc-free method for dedicated monitoring of a
specific gas or vapor. Its design combines a hardware/electronic/software package with a measurement principle that can be easily applied to meet a variety of application needs. The analyzer does not require the use of any consumable items other than zero gas and particulate filters, which eliminates the need for purchasing a large quantity of other supplies to keep the InfraRan Analyzer operable.
Economical Monitoring
The analyzer uses a nondestructive measuring principle and only requires a source of power for operation (internal battery pack or external operating supply - 120-220 VAC, 50/60 Hz). Since the analyzer is factory calibrated for one specific vapor or multiple gases (depending on the model selected), recalibration by a trained technician is not required for most applications. With its menu-driven software, direct-reading display, and simple controls, minimal - if any - training is required to operate the analyzer. Thus, monitoring costs with the InfraRan Specific Vapor Analyzer are very low compared to other analytical methods or instrumentation.
Lightweight & Portable
The analyzer weighs 18 lbs. With its internal battery power, the InfraRan Analyzer is truly a portable instrument. It can run up to 8 hours on its battery pack, and includes internal data logging for added measurement and record keeping convenience. No additional equipment is necessary since all supplies that are required for monitoring are included. The InfraRan Specific Vapor Analyzer can be factory-calibrated for most compounds that have an infrared absorption band in the 2.5 µm - 14.5 µm region.
The compound and concentration range must be specified at the time of purchase. Standard multiple gas models are available for measuring refrigerant or anesthetic gases. Easy to Use
The InfraRan Specific Vapor Analyzer is factory-calibrated so that no chemical standards are needed by the user to calibrate the analyzer. It's user-friendly, menu-driven software and easy-to-read display prompt the user through all aspects of the analysis - enabling both non-technical personnel, as well as those with an infrared gas analysis background, to make fast, accurate measurements.
