The orifice plate is the opening where ions enter the mass spectrometer, which is one the of key component in the mass spectrometer. The fuction of the orifice plate is with a voltage applied to it and to help preventing ions from clumping together. The good orifice plate should included below factors 1.Detachable heater It is using MCH heater which is the abbreviation of metal ceramic heaters. It refers to a ceramic heating element in which a meta tungsten or molybdenum manganese paste is printed on a ceramic casting body and laminated by hot pressing and then co-fired at 1600°C, in a hydrogen atmosphere to co-sinter ceramic and metal. MCH ceramic heating element is high-efficiency, environmentally friendly, and energy-saving. MCH Heater has below advantages Energy-saving, high thermal efficiency, unit heat power consumption is 20-30% less than PTC; The surface is safe and non-harged, with good insulation performance, can withstand the withstand voltage test of 4500V/1S, no breakdown, and leakage current <0.5mA; No impulse peak current; no power attenuation; rapid heating; safe, no open flame; Good thermal uniformity, high power density, and long service life. The most important is for heating evenly, so MCH heater perform very good in this factor. The detachable heater design in orifice plate is very economical and practical, and when the heater fails, it can be easily replaced and used, saving the cost and time of replacement.
