MCH heater (Metal Ceramic Heater, a high-performance ceramic heating solution specifically designed for mass spectrometers and analytical instruments) can be used as a source heater or a gas channel heating element. It rapidly and uniformly heats liquid or gas samples to an gaseous state, allowing them to enter the analysis section. Compared to traditional resistance wires or PTC elements, MCH heaters have a smaller size, higher energy efficiency, precise temperature control, and quick response. This helps to enhance the sensitivity and accuracy of mass spectrometry analysis while ensuring a pollution-free heating process.
