Rinse Procedure for the Marin-5 Glassware
The Marin-5 glassware may need to be thoroughly rinsed after the
analysis of organic samples containing high concentrations of
nonvolatile residues or after analysis of aqueous samples containing
high concentrations of dissolved solids. The length of time between
rinses in a routine operation depends on the types of samples analyzed.
Analysis of samples containing less than 1% of dissolved solids is
recommended. Best performance will be achieved with 0.1% to 0.5%
dissolved solids.
Note:
If aqueous samples were analyzed, 2% HNO3 may be used to rinse
the glassware. If organic solvents such as toluene or hexane were
analyzed, rinse the glassware with 2-propanol. If non-volatile
organic samples (e.g., oils diluted in an organic solvent) were
analyzed, rinse the glassware with toluene or hexane. After rinsing
with such a solvent, perform a second rinse with 2-propanol.
WARNING
Please observe any necessary safety precautions (safety glasses,
gloves, etc.) when handling HNO3 solutions and organic
solvents.
Note that the Marin-5 glassware consists of a spray chamber and an
initial desolvation section. The spray chamber and the desolvation
section are one continuous piece of glassware. Please refer to Figure 6-1
for an interior picture of the Marin-5.
