Other Environmental Conditions
Chemicals
Use, store, and dispose of chemicals that you require for your analyses in accordance with
the
manufacturer’s recommendations and local safety regulations.
Warning!
Some chemicals used with this instrument may be hazardous or may become
hazardous after completion of an analysis. The responsible body (for example, Laboratory
Manager must take the necessary precautions to ensure that the surrounding workplace
and instrument operators are not exposed to hazardous levels of toxic substances (chemical
or biological as defined in the applicable Material Safety Data Sheets (MSDS or OSHA,
ACGIH, or COSHH documents.
Venting for fumes and disposal of waste must be in accordance with all national, state
and local health and safety regulations and laws.

Toxic Fumes
If you are working with volatile solvents or toxic substances, you must provide an efficient
laboratory ventilation system to remove vapors that may be produced when you are
performing analyses.
Waste Disposal
Waste containers may contain corrosive or organic solutions and small amounts of the
substances that were analyzed. If these materials are toxic, you may have to treat the
collected effluent as hazardous waste. Refer to your local safety regulations for proper
disposal procedures.

System Des ription
The SPM301 is compact NIR spectrometer operating in the 1000-3000nm range. The
spectrometer features a 256 pixels PbS array detector spectrometer (SM301), a broad band
tungsten-halogen light source, and a cuvette holder.
This instrument is usable in a wide range of applications requiring fast measurements.
Opti al System
The SPM301 compact near infra-red spectrophotometer features an array detector based
spectrometer system.
The optical system is depicted schematically in figure below.
5
The PbS array spectrometer is based on a crossed Czerny-
Turner configuration and consists of an entrance slit, a
gold coated collimating mirror, a grating, a gold coated
focusing mirror a gold coated bending mirror, and 256
pixels PbS array detector.
The detector array is thermoelectrically cooled ensuring
long-term operating stability. A tungsten halogen lamp is
used as the light source and is stable after a power-on
warm up period of about ten minutes. The instrument has
been uniquely designed without moving parts, providing
enhanced signal/noise and sensitivity and incorporates
readily available industry standard components.

System Installation
Equipment Provided
Please check that you have been shipped a SPM301 plus the components listed below.
Item 1: Main SPM301 spectrophotometer, 1ea
Item 2: Software package, SM32Pro For SM301 1ea
Item 3: Cuvette holder included in the SPM301 1ea
Item : Optical glass cuvettes, 2mm path length 2ea
Item 5: Power cable 1ea
Software Installation
Before plugging the SPM301, the operating software, SM32Pro for SM301, has to be
installed on your computer first. Please refer to the software manual. After installing the
software properly, please connect the spectrophotometer.
Conne ting to the line power supply
Warning!
To prevent potential injury to yourself and damage to the instrument, first make the
electrical connections between the instruments in the system before connecting to the line power supply.
1. Make sure that the correct fuse is fitted in the holder at the side of the SPM301.
2. Make sure that the plug fitted to the line power cord provided with the spectrometer
is suitable for your local electrical outlets. If it is not, remove it and fit plug
conforming to the local regulations.
3. Make sure that the power switch is set to off, then connect the line cord to the
electrical power supply. The power switch is located at the side of the spectrometer,
right above the power cord connector.
NOTE!:
To prevent interferences caused by earth loops when operating with ancillary instruments
(for example, printers , connect all components of the system to the same phase of the electrical supply
via a multisocket distributor.
