ISDP⁺
Internal Standards and Dry Purge
The GERSTEL ISDP and ISDP⁺ can spike each thermal desorption tube with a known, fixed amount of gas or liquid standard; then, each tube is purged with a drying gas to remove water captured in the tube when humid air is sampled or solvent if the tube is spiked with liquids.
ISDP⁺
The GERSTEL ISDP⁺ is a versatile and fully automated solution for highly reproducible spiking of 3.5” TD tubes, including GERSTEL 3.5⁺ tubes, with liquid or gaseous standards. The fast and efficient dry purge function eliminates doubt when analyzing samples with high moisture content while maintaining high throughput. The GERSTEL ISDP⁺ provides both standard spiking and dry purge functions for 3.5” TD tubes, including GERSTEL TD 3.5⁺ tubes. The GERSTEL ISDP⁺ meets the requirements and recommendations of standard TD methods, extending the scope of your TD analysis and making it more efficient.
Main Features and Advantages
- Fully automated spiking of
calibration/QC/validation standards - Higher data quality when using internal standards
- Gas or liquid standards can be used, utilizing syringes to inject
either fixed or variable volumes of standards - Improved performance and quality with dry purging
Eliminate time and effort in spiking tubes for both targeted (regulated) methods and non-targeted methods.
GERSTEL’s advanced ISDP⁺ system uses the latest in flow control technology. It allows the use of gas and liquid standards and eliminates the time required to build calibration curves and manually spike tubes.
