Acid Purification for ICP-MS
The increasingly lower limits of detection available with ICP and ICP-MS
require ultra pure matrices. Sub-boiling acid safely allows you to prepare
ultra pure acids right in your laboratory at a fraction of the cost of
purchasing these regents. The distillation method of surface evaporation
without boiling is employed through the use of heaters. Most metals can
be reduced below parts per billion in a single distillation.
The PTFE sub-boiling acid still handles all common acids
except sulfuric and can produce up to 50ml per hour of operation. Liquids
and vapors come in contact with PTFE and PFA Teflon only to produce ultra
pure acids.

Converts standard purity acids to ultra pure in your
laboratory, usually paying for itself in the first year.

With
trace analysis ultra pure acids are more and more common in graphite furnace
atomic absorption and in ICP-OES and ICP-MS techniques. With this acid
purifying apparatus ultra pure acids can be produced out of standard qualities
or pure water out of polluted water. Dirty acids can be cleaned several
times. The sub- boiling consists of an IR-radiant heater and a PTFE vessel
as steam chamber with PFA-cooler. The condensate will be led exclusively
via PFA and stored in a translucent PFA-container.

For an analytic decomposition substances are needed which
have no numerical result in a blank test. In this case it is of advantage
to distill the required acid fresh. Only thereby can any contamination
by storage be avoided.
