Corrosion - PerkinElmer 200 UV/VIS Series User Manual

Safety and Regulatory Information

Corrosion

The following corrosion precautions apply to the standard (stainless steel) UV/VIS and the
biocompatible (titanium) UV/VIS Detectors.
Standard
All parts of the Series 200 UV/VIS Detector that contact mobile phase are made of stainless
steel, KelF, and quartz. Some of these materials are extremely sensitive to acid chlorides. If
you have questions about your mobile phase or flush solvent, contact a PerkinElmer repre-
sentative. Refer to the table below.
Table S-1. Solvents Which May Corrode the Series 200.
Aqua Regia (80% HCl, 20% HNO3)
Hydrogen Peroxide
Anhydrous Chloride
Dichloromethane
Sulfuric Acid (Conc.)
Hydrochloric Acid (20% and 37%)
Hydrofluoric Acid (20%, 50%, and 75%)
Copper Chloride
Biocompatible
All parts of the Series 200 UV/VIS Detector that contact the mobile phase (from the pump)
and flush solvent are made of titanium, fluoropolymers, or glass. This makes the Series 200
UV/VIS Detector inert to the most common mobile phases that are used for biological assays.
If you have questions about your mobile phase, contact a PerkinElmer representative. Refer
to the table below.
Table S-2. Solvents Which May Corrode the Series 200.
Aqua Regia (80% HCl, 20% HNO3)
Hydrogen Peroxide
Dichloromethane
Aqua Regia and sulfuric acid are known to
dissolve titanium.
Anhydrous Methanol
Chlorinated solvents
Sulfuric Acid
