Apex IR Desolvating Nebulizer

The Apex IR desolvating nebulizer was 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.

• Improves sensitivity 3–10 fold depending on sample flow rate.
• Supplied with 2 PFA MicroFlow nebulizers
• O-ring free Quartz sample flow path
• Flow rates from 20 - 600µL/min
• Dual preset temperature settings for heater (100°C / 140°C) and cooler (-3°C / +2°C)
• Nitrogen addition control
• Retrofit to Apex Q version
