The principle component of a quadrupole mass spectrometer is the mass filter which is used to filter ions with different charge to mass ratios. The quadrupole mass filter has been well studied over the years, Ref. 1 and the physics and optimal design are well understood. In a real ... En savoir plus
Composite materials are often used in structural applications because their properties, such as stiffness and strength, can be tailored to meet specific requirements. This makes them attractive alternatives to traditional engineering materials. Composites are also used in applications ... En savoir plus
Inductors are used in many applications for low pass filtering or for impedance matching of predominantly capacitive loads. They are used in a wide frequency range from near static up to several MHz. An inductor usually has a magnetic core to increase the inductance, while keeping its ... En savoir plus
