Cleaning the Burner Chamber After Use With Organic Solvents
If you aspirate aqueous samples immediately after organic samples (e.g. oils or
MIBK extracts), the absorption signals can be noisy and erratic. After aspirating
organic samples, perform the procedure below to prevent contamination of
subsequent aqueous samples.
1. Aspirate for 5 minutes an organic solvent that is miscible with the samples that
have just been aspirated.
2. Aspirate methanol or another solvent miscible with both the organic solvent
and water, for 5 minutes.
3. Aspirate 1% nitric acid solution for five minutes.
4. Flush the drain tube thoroughly with water. Empty the collection vessel and
refill with water. Dispose of hazardous or corrosive solutions properly and
observe local codes concerning the effect of the waste on the environment.
Note
If the solid deposits cannot be removed with a soft brush and a mild
laboratory detergent solution, the internal cavity of the chamber may be
soaked overnight with the 0.5% Triton X-100 + 5% HNO

acid when the
opening for the burner head is closed. Thoroughly rinse the internal cavity
with de-ionized water before use. If solid deposits still remain, you will
need to replace the spray chamber.
