HiSorb high-capacity sorptive extraction – Lower detection limits than SPME
What is HiSorb?
HiSorb™ is a high-capacity sorptive extraction technique for use with thermal desorption–gas chromatography–mass spectrometry. Robust metal HiSorb probes support a high-capacity sorptive phase, which extracts volatile and semi-volatile organic compounds (VOCs and SVOCs) from solid, liquid and gaseous samples using either headspace or immersive sampling.
Why use HiSorb?
- A flexible alternative to methods such as stir-bar sorptive extraction
- Detection limits are lower than for SPME because of the larger capacity of sorptive phase
- Easier and quicker to use than solvent extraction
- Re-usable probes and tubes minimise the cost per sample
- Robust and easy to use with multiple phases available
Where to use HiSorb
HiSorb probes and accessories, designed for research analysts, are ideal for trace-level component characterisation, aroma profiling, quality control and advanced research across a wide range of applications such as:
- Beverages – aroma-profiling of tea, coffee, fruit juices, wine, spirits and milk.
- Water – detection of off-odours in drinking water and pollutants in watercourses.
- Fragranced goods – profiling of aroma-active compounds in personal care products.
- Clinical research – analysis of bodily fluids for disease markers.
- Foodstuffs – dairy products, fruit/vegetables and dried goods.
HiSorb probes are available in four phases:
- PDMS Suitable for volatiles to non-polar semi-volatiles
- PDMS/CWR Suitable for lower molecular weight compounds
- PDMS/DVB Suitable for volatiles, amines and polar compounds
- DVB/CWR/PDMS Suitable for volatiles, semi‑volatiles and flavour compounds
