PolyCon - for routine high precision HF analyses
The PolyCon concentric nebulizer represents the choice nebulizer for high precision analyses involving samples digested in HF. The PolyCon has been used successfully in ICP desolvators such as the MCN-6000, where high temperatures are encountered. It has become a favourite in the semi conductor industry, and has enabled analysts to produce accurate (r = 0.9998) calibration curves for low-ppt levels of Na, K, Fe and Ca in 30% hydrogen peroxide.
- Material: HF Resistant Polyimide
- High physical reproducibility ~ 2%
- High tolerance to particulates, up to 75um depending on uptake
- TDS tolerance, typically ~5%
- Low RSD's due to concentric geometry
- Uses only standard ICP argon supply pressures
- Standard 6mm size fits standard cyclonic spray chambers. Adaptors are available for Scott type spray chambers
- Standard available uptakes: 0.05, 0.1, 0.2, 0.4, 0.6, 0.8, 2 & 5ml/min for samples with large particulates
PolyCons with sample uptakes 0.05 - 0.1ml/min are supplied with 1 x NFT-025, UniFit Connector with 1.3mm OD x 0.25mm ID x 700mm long sample tubing.
PolyCons with sample uptakes 0.2 - 0.8ml/min are supplied with 1 x NFT-050, UniFit Connector with 1.3mm OD x 0.50mm ID x 700mm long sample tubing.
PolyCons with sample uptake 2ml/min are supplied with 1 x NFT-075, UniFit Connector with 1.3mm OD x 0.75mm ID x 700mm long sample tubing.
