ModelsThe Apex sample introduction system is available in four basic models: Apex E, Apex Q, ApexHF, and Apex IR.The Apex E has been primarily designed as an inlet system for ICP-AES. the Apex E is very simpleto use with only 1 switch operation and has a Pyrex flow path to produce a relatively low cost,high sensitivity inlet system. The Apex E is supplied with either PolyPro-ST of PFA-ST nebulizers.The Apex Q has an o-ring-free quartz flow path for high sensitivity and low background forsamples that do not contain hydrofluoric acid. The Apex Q gives the fastest rinse-out of any highsensitivity ICP introduction system. Two MicroFlow PFA nebulizers are included with the Apex Q.The Apex HF uses a high-purity PFA Teflon flow path to provide resistance to hydrofluoric acid.The Apex HF is recommended for many geochemistry and semiconductor applications wheresamples containing HF are analyzed. Two MicroFlow PFA nebulizers are included with the ApexHF.The Apex IR has a quartz flow path and includes the ApexAreo membrane desolvation modulefor reducing ICPMS spectral interferences that arise from solvent-derived polyatomic ions. ThreeMicroFlow PFA nebulizers: 50, 100, and 300 µL/min are included with the Apex IR.Performance DataThe patent pending design of the sample flow path ensures minimal memory effects with rinseoutscomparable if not faster than simple cyclonic systems, even with initial higher count rates.
