Spectrolab Systems offers Optical Emission Spectrometers which fall into two broad categories, depending on the detection systems used.
Photomultiplier Tube (PMT) based systems use a single element detector per wavelength and are physically bigger in dimension that CCD based systems. However they offer very high sensitivity and high S/N ratio, which results in much lower Limits of Detection (LOD). They offer best efficiency in the ultra-violet (UV) region.
Spectrolab offers the following models based on PMT technology:

| ATLANTIS | F-20 | METAL-LAB |
Charged Couple Device (CCD) based system use an array of detectors and hence sample the entire spectrum simultaneously. It is possible to subtract background or reference spectra from the sample spectra to give much cleaner data. However CCDs often have much higher dark noise/electronic noise, resulting in diminished S/N ratio hence poor Limits of Detection (LOD). Multiple integration is required to pick up information from weaker lines.
