INTRODUCTION
GENERAL DESCRIPTION
The MIRAN SapphIRe family of lightweight portable ambient air analyzers consists of a
group of infrared instruments that can monitor ambient air in workplace environments for
the purpose of detecting the presence of gases (Figure 1-1). The family includes three
models, all of which are available in intrinsically safe versions. Some of the major
differences among models are shown in Table 1-1.
Figure 1-1. SapphIRe
Table 1-1.Feature Comparison of Various Models
Feature SapphIRe Analyzer Model
DL SL XL
Factory calibrated for number of gases listed 0 50 120
User library of 10 single gas and 10 multi-gas applications Yes Yes Yes
Alternate measurement wavelengths No Yes Yes
Fully upgradable to other models Yes Yes N/A
Temperature/humidity/reference compensation Yes Yes Yes
Field calibration by user Yes Yes Yes
In addition to the features noted in Table 1-1, all instrument models may be configured
with two options that must be installed at the factory. These are intrinsic safety
certification and spectral scanning using the ThermoMatchSpectrum Correlation
Software.

Chapter 1 Introduction
1-2
Each SapphIRe analyzer contains a single-beam infrared spectrophotometer. A
microcontroller automatically controls the analysis, processes the measurement signal,
and calculates the absorbance values. Analysis results can be displayed in parts per
billion (ppb), parts per million (ppm), percent (%), mg/m3, or absorbance units (AU).
Warning: Intrinsically safe models require special actions with respect to the following
section. Refer to Appendix B for descriptions of these actions.
A rechargeable internal battery pack provides power for up to four hours of continuous
operation. The system includes a separate charger/power supply (Figures 3-5 and 3-6)
that allows the analyzer to be powered from an ac supply. It is also used to recharge the
battery pack either in an offline mode or while the analyzer is running in normal
operating mode.
SapphIRe-DL Analyzer
The SapphIRe-DL Analyzer has the ability to measure any compound having an
absorbance in the wavelength region from 7.7 microns to 14.1 microns or any of the
available fixed band pass filters, such as carbon monoxide, carbon dioxide,
formaldehyde, nitrous oxide, hydrocarbons, water, and reference. The SapphIRe-DL
Analyzer provides the ability to perform multicomponent analysis. It can take
absorbance measurements of up to 10 wavelengths, and display and log compensated
concentrations for up to five individual gases. In addition, its user library can be
programmed to store up to 10 single gas applications and up to 10 multi-gas applications.
SapphIRe-SL Analyzer
The SapphIRe-SL Analyzer performs all the functions of the SapphIRe-DL Analyzer. In
addition, it has 50 single gas factory calibrations in its standard library, many employing
an alternate wavelength (see Appendix H). These calibrations allow the selection of a
compound from its standard library of gases. The analyzer then "pulls up" the
application information, configures itself to measure the compound of choice, and
delivers concentration readings for this compound without performing interference
compensation. This avoids interference from other gases by selecting a different
measurement wavelength for a given gas instead of going through full multicomponent
calibration. This feature is beneficial when two different gases have spectra that both
exhibit peaks at some wavelengths but not at others. By selecting a measurement
wavelength for the target gas that is not common to any other gas, the interference
problem can be avoided.
SapphIRe-XL Analyzer
The SapphIRe-XL Analyzer performs all the functions of the SapphIRe-SL Analyzer,
except it has more than 120 single gas factory calibrations in its standard library (see
Appendix H).
