HEY...JUST WONDERING IS THERE A BIG OPERATIONAL DIFFERENCE BETWEEN ICPMS AND THE OTHER MS LIKE GC AND LCMS?

I would say there is a significant difference. Probably depends on how you define "big."

When, u said MS, u r referring to one term MASS SPECTROMETER (that is a detector)..
but if u said GC-MS u r refering to the GAS CHROMATOGRAPHY (analytical instrument) WITH MASS SPECTROMETER (detector)..
When u change the word to ICP-MS.. it does mean Induced Coupled Plasma (analytical instrument) with Mass Spectrometer (detector)..
So, the different is the type of analytical instrument... the only same thing they have is the detector (MS)..

Well for ICP-MS trace analysis you will need a clean room to operate in, requirements could look like this:
- Indoors (really
)
- Free of smoke, dust and corrosive fumes
- Not prone to excessive vibration
- Out of direct sunlight
- Away from heat radiators
In order to minimize contamination problems, a
dust-free environment is necessary. For ultra-trace
techniques, environmental contamination becomes a
limiting factor in the analysis. To quantitate ubiquitous
elements such as Fe, Ca, K, Na, etc. below 1 ppb (μg/L),
a class 1000 environment is necessary for sample
preparation and analysis. This is not an indication of
the performance limitations of the instrument, but
a recommendation for an ultra-clean environment.
