What are the common contaminants in my GCMS

Title: What are the common contaminants in my GCMS Contamination is usually identified by excessive background in the mass spectra. It can come from the GC or from the MSD. The source of the contamination can sometimes be determined by identifying the contaminants. Some contaminants are much more likely to originate in the GC.

sorts the ions based on their mass-to-charge ratio. Inductively coupled plasma mass spectrometry (ICP-MS) is a type of mass spectrometry which is capable of detecting metals and several non-metals at concentrations as low as parts per billion on non-interfered low-background isotopes. Introduction

the signal is small relative to the background. It is common to express the relationship between signal and background as the “signal-to-background ratio” or S/B. (This is often referred to as “signal-to-noise” or S/N, but background and noise are two distinct characteristics). The above example would have an S/B of 0.1.

Section 1: Introduction to Radioactive Materials

More than 80% of the radiation we are exposed to comes from “background” radiation---natural sources like sunlight, soil and rocks. Most remaining exposure come from manmade sources, such as x-rays and common household appliances like smoke detectors and color televisions. Table 1.1 shows the average annual dose from natural background ...

X-ray Photoelectron Spectroscopy

Another technique that employs ions for bombardment is ion scattering spectroscopy (ISS), which, as its name implies, measures the energy change as different ions are scattered off a surface. ISS is so surface­sensitive that sample contamination can be a serious problem; with careful use, however, ISS can be a useful companion
