Do NOT operate the Model 2120XL Trace Nitrogen in Argon
Gas Analyzer until you read and understand the operating,
maintenance, and safety instructions included in this
manual.
Anyone involved with the operation of this equipment
including plant engineering, operations, and management, must
understand the potential hazards involved, and know and observe all
required safety precautions.
Your safety and the safety of equipment, nearby facilities, and
personnel require a proper safety attitude and emphasis on safe work
procedures. This is the essence of any good safety program. If at any
time you identify safety deficiencies, immediately correct them and
bring them to the attention of management.
Before an accident can be prevented, it must be anticipated. Use
pre-job discussions with your coworkers and supervisors to identify
hazards and the means to avoid them. At your facility, various gases
may exist in liquid and/or gaseous states. Familiarize yourself with the
hazards associated with each gas found at your facility.
Read and understand the Material Safety Data Sheets (MSDS) for
the materials used with this equipment. All personnel who work in the
vicinity of this equipment should read, understand, and follow all safety
information contained in the MSDSs, in addition to following all
government and facility safety regulations.
CAUTION: NEVER INTRODUCE GASES OTHER THAN ARGON
INTO THE ANALYZER. IF EXPLOSIVE, FLAMMABLE,
OR CORROSIVE GASES OR GAS MIXTURES ARE
ALLOWED TO FLOW INTO THE ANALYZER, FIRE OR
EXPLOSION CAN RESULT. THIS ANALYZER IS NOT
DESIGNED TO BE USED IN HAZARDOUS AREAS.
1.7.1 Detector Cautions
The Model 2120XL uses a detection technique based on
spectroscopic emission. The detector is a thin-walled pure quartz cell
located in an electromagnetic field created by a specific high intensity
plasma generator. This electromagnetic field creates a plasma that emits
light at different wavelengths. A filter for the nitrogen is used to avoid
any interference and get the best performance.
