Perkin Elmer/Sciex - Model 201 -ICP-MS Electron Multipliers Used in the Sciex ELAN5000 (Unmounted), 500 & 200
DeTech multipliers are manufactured from a lead glass suitably processed to yield an efficient secondary emitting layer on the inner surface. Each electron multiplier is tested before shipment to ensure its performance is within specification. Each multiplier is delivered with a quality control label indicating its model number, test voltage, gain at that voltage, bias current at the test voltage and the date of shipment.
