HS-20 NX series - Funzionalità
Headspace Sampler
Next Level Performance
Ultra-low carryover
The HS-20 NX series uses the isolation gas flow to reduce carryover to 1/10 of conventional models. It supports a wide range of chemical species, including high-boiling point compounds and high-polar compounds, and provides reliable analytical results.
Negligible carryover
The Isolation Gas Flow
The isolation gas flow prevents sample diffusion from the vent channel, which has been a problem with conventional headspace samplers. (patent pending) Carryover of highly adsorptive compounds is reduced, eliminating the need for
repeating blank runs.
Residual Solvents Analysis in Pharmaceuticals
USP <467>
In the residual solvents analysis of medicines, analysis with an aqueous solvent may be performed after analysis with a DMF solvent, but with the HS-20 NX, carryover of DMF is not a problem. HS-20 NX is effective for the analysis of samples with different type of solvents or large concentration differences.
Excellent reproducibility
Ethanol area reproducibility
0.7 % or less (N = 6)
High analysis reproducibility is achieved by the sample vial loading from the lower part of the oven. Shimadzu's unique sample vial delivery system minimizes heat dissipation in the HS oven as the vial enters and leaves the oven, and maintains high temperature stability during repeated analyses.
High temperature capability and short inert flow path
The vial oven and sample line can be set to 300 °C and the transfer line can be set to 350 °C. In addition, the sample path is designed to be inert and at the shortest distance, so that adsorption of analytes, including high-boiling compounds, and peak broadening are suppressed.

Achieved high recovery rate even for high-boiling point compounds.
Ready to use an alternative carrier gas
The HS-20 NX series with the latest electronic AFC (Advanced Flow Controller) offers highly accurate carrier gas control at constant linear velocity, constant flow, and constant pressure modes. It supports the use of nitrogen and hydrogen as alternative carrier gases and makes it easy to transfer analysis methods.
Superior Usability
Simplifies the column connection
ClickTek™ NX Connector
ClickTek, adopted by Nexis™ GC-2030, has been optimized and applied to the HS-20 NX. ClickTek NX enables anyone to connect columns easily and without tools, simplifying column replacement and routine system maintenance.
Improved lab productivity
-
Easy access and automatic overlap analysis
The HS-20 NX features a vial tray for easy access. In addition, up to 12 vials can be kept warm in the HS oven, increasing laboratory productivity with automatic overlap analysis that optimizes the total analysis time, even for methods that require longer vial heating times.
-
Beyond Expectation
With the trap mode of the HS-20 trap model, which can concentrate samples, 10 - 100 times more sensitive analysis can be achieved than with the loop mode. The HS-20 trap model also operates in the loop mode, giving users the flexibility to meet multiple analytical requirements.
