vi Electrostatic Classifier Model 3082 and SMPS Spectrometer Model 3938
L a s e r S a f e t y
The SMPS 3938 system includes a Condensation Particle Counter (CPC)
which is a Class 1 laser-based instrument. You will not be exposed to laser
radiation during normal operation of the Model 3772, 3775, 3776, 3787, or
3788 CPCs. However, you must take the following precautions to prevent
exposure to hazardous optical radiation in the form of intense, focused,
invisible light:

Do not remove any parts from any CPC unless this manual instructs
you to do so.

Do not remove any part of the CPC housing while the instrument is
powered on.
W A R N I N G
The use of controls, adjustments or procedures other than those
specified in this manual may result in exposure to hazardous optical
radiation.
R a d i a t i o n S a f e t y
The 3938 SMPS spectrometer can be used with a Model 3077 or 3077A
Neutralizer (contains a Krypton-85 source). The following precautions must
be taken when using the Model 3077/3077A Neutralizer:

Do not remove any parts from the 3082 Classifier unless this manual
instructs you to do so.

Corrosive materials can degrade materials within the classifier. Do not
operate the classifier and its associated instrumentation with chemicals
that corrode 303, 304, or 316 Stainless steel, copper, silver solder, or
epoxy.

A lead radiation shielding (optional accessory) may be installed inside
the Electrostatic Classifier Model 3082. This shielding will reduce the
radiation level to <1 µSv/hr at a distance of 10 cm from any touchable
surface of the classifier. In some countries or localities, the Model
3077A neutralizer must be operated with lead shielding installed.

Temperatures above 50°C may cause the 3077/3077A neutralizer to
leak, causing radioactive contamination. Do
not operate the classifier
or its associated instrumentation in temperatures above 50°C.

Keep all Neutralizer packing materials. The neutralizer has a half-life of
10.7 years. TSI recommends that after 10 years of operation you return
the neutralizer to the manufacturer and replace it with a new one.

Install and remove the neutralizer using the directions contained within
this manual.
