used at temperatures less than 135°C, they can withstand repeated exposure
to the following substances:
Predominantly aqueous solutions of acids (less than 10%), including HNO
3
and HCl.
Predominantly aqueous solutions of strong bases (less than 10%)
Common organic solvents such as acetone, alcohols, ethyl acetate,
Methylethylketone (MEK), petroleum oils and derived fuels,
tetrachloroethylene, toluene, kerosene and xylene.
NOTICE
DAMAGE FROM CHEMICAL EXPOSURE
Prolonged or repeated exposure to temperatures greater than 135°C and to
the following substances can cause failure of the wetted components:
Acids greater than 10%.
Hydrofluoric acid (HF).
Solutions of concentrated bases (greater than 10% potassium,
ammonium, or sodium hydroxides).
Partially halogenated hydrocarbons or extremely aggressive organic
solvents (chloroform, methylene dichloride, 1,1,2-trichloroethane).
Operator Qualifications
To use this product, you should have a working knowledge of the equipment
with which the syringe module will be used.
WARNING
CHEMICAL INJURY HAZARD
Make sure you know the hazards associated with all of the chemicals you
are using, and take the appropriate precautions. Exposure to laboratory
chemicals may result in serious injury.
Choosing a Location for Installation
Proximity to the Instrumentation
Tubing length affects the time it takes for fluid to reach its destination and the
volume of fluid required. When introducing very small sample volumes (flow
rates less than 50 µL min
-1
), minimize the length of the connecting sample
tubing. For the introduction of sample volumes to analytical instrumentation
such as ICP-MS, where flow rates of greater than 50 µL min
-1
will be employed,
the length of connecting sample tubing between the syringe pump and a
nebulizer is less critical. The syringe module can be mounted on either side of
the autosampler or it may be placed on the workbench.
