Analytical Instrumentation ULTRAMIC® Advanced Ceramic Heater Application Mass spectrometers are used to determine the presence of trace chemicals in industrial, environmental and clinical applications. The technique involves using high heat to desolvate the ionized sample prior to its entry into the spectrometer. Traditional heating methods include use of cartridge or cable heaters to heat a metal assembly that, in turn, conducts the heat to a stream of high-purity inert gas. Design Requirements Mass spectrometers have detection capabilities into the part-per-trillion levels for most analytes and as such, a non-contaminating thermal source is imperative. Also, instrument designs are being challenged with the competing requirements of reducing size and complexity,while still improving sensi
