quadrupolefor analysis

Components for Cluster Studies The Hiden cluster components include 9mm and 20mm pole diameter quadrupole assemblies with high-power RF operating at optimum frequency to accommodate high mass transmission required in cluster analysis. The upper mass limit of a Quadrupole filter is severely constrained by the demand for RF Power that accompanies increasing m/z. Down-sizing the Rod Diameter appears to offer a way around this problem, but comes with a significant reduction in Quad performance, limiting its effectiveness for clusters at high m/z. Hiden’s High Power RF Generator provides the solution – it is capable of delivering 5,000 m/z mass range even on a 9 mm Triple Filter Quad and with a frequency of 0.8 MHz, a combination that generates outstanding performance. This brings transmission of 45% at 5,000 m/z, yielding the lowest detection limit even for the largest of clusters. Hiden’s unique combination of Triple Filter, 9 mm Rods and High Frequency RF Generator, creates exceptional resolving power, even at the highest m/z. Flexibility – optimises the balance between Resolving Power and Mass Range With our new 20 mm Tri-Filter quadrupole and 400 kHz RF head we achieve a mass range of up to 4,000 amu and with our 9 mm Tri-Filter a mass range of up to 20,000 amu.
