四极质量分析器早已脱离它的最初应用。早期是作为同位素分离使用的,目前四极已应用在质谱法的各个方面。由于四极分析器的体积小,重量轻,价格较低,还因为四极具有检测多种来源的离子和中性粒子的独特能力,所以才获得了上述的成就。 Quadrupole mass analyzer has long since been its initial application. Early use as isotope separation, the current quadrupole has been applied in all aspects of mass spectrometry. The above achievement has been achieved due to the small size, light weight and low cost of the quadrupole analyzer, as well as the unique ability of the quadrupole to detect ions and neutrals of various origins.
