Elemental Scientific (ESI) products

The Apex Q has an o-ring-free Quartz flow path for high sensitivity and low background for samples that do not contain hydrofluoric acid. The Apex Q gives the fastest rinse-out of any high sensitivity ICP introduction system.

Low cost unit primarily designed for ICP Emission systems. The sample path is made from Pyrex and temperature settings of the heater and chiller are fixed. ICP-AES detection limits can be improved by up to a factor of 6-10 when operating at 1 ml/min using a MicroFlow PFA-ST or PolyPro-ST nebulizer together with the Apex E. Alternatively, the combination of a low flow nebulizer with the Apex E maintains ICP-AES sensitivity while reducing sample consumption by a factor of 5 to 10, improving ICP-AES determinations when the volume of sample is limited.

The Apex IR has been developed for Isotope Ratio analysis. It has a quartz flow path and includes an additional mixing chamber that further homogenizes and stabilizes the sample aerosol stream, resulting in a more stable signal from the ICP-MS.

The PFA-ST Nebulizer features the same high purity, HF resistance, and high performance of the PFA MicroFlow nebulizers, along with an exchangeable external sample uptake capillary. The sample uptake rate is controlled by the dimension of the external capillary or probe.

An integrated capillary PFA nebulizer for self aspiration. PFA MicroFlow nebulizers are constructed entirely from chemically resistant fluoropolymers, ideal for strong acids, alkalis, organics and high salt solutions. They are resistant to clogging, and produce a fine aerosol for high transport efficiency and high sensitivity.
