/Resources 36 0 R IR spectra water, in view getting some insight into the disposition and dynamics of H~O molecules in water. Keep in mind there will always be some amount of water around, unless of course you're doing this in a glove box. /CropBox [0.0 0.0 510.0 708.48] A number of different approaches can be used for monitoring moisture contamination, depending on the machine’s criticality, the risk of failure and the available resources. Knowledge on this recently considered contamination has been constantly growing, although the studies are mainly oriented toward marine environments.
