Column sets and commitment to excellence
The GO-EHT sample preparation systems are operated with a certified set of four chromatography columns for every sample. These high performance clean-up columns are vacuum sealed and have a user-friendly design.
During the purification process, the columns are heated which results in a significant boost in chromatography efficiency while using a very low volume of organic solvent. Exposure to operator and the environment is minimized.
GO-HT column sets are suitable for food, feed and environmental matrices. One complete set consists of 4 different columns plus tubing:
- Silver nitrate impregnated silica column
- Sulphuric acid impregnated silica column
- Aluminum oxide concentration column
- Carbon/florisil concentration column
- Tubing set
Depending on the nature of samples and desired column set capacity we provide the following types of column sets
| Cat. Number | Product description | Capacity | Application | Delivery time |
| X300-002-2420-7 | 20φ Column set (DXN/PCB) | < 4g fat | Dioxins, PCB, PBDE, PCN | 1 week |
| X300-002-1320-7 | 18φ Column set (DXN/PCB) | <1g fat * | Dioxins, PCB, PBDE, PCN | 4-6 weeks |
| X300-002-1330-7 | 18φ Column set (DXN) | <1g fat ** | Dioxins only | 4-6 weeks |
* For analysis of Dioxin and PCBs in environmental samples and/or samples with low fat content (<1g)
** For analysis of Dioxins only in environmental samples in and/or samples with low fat content (<1g)
Quality Control
Miura Co. Ltd. in Japan is an ISO 17025 accredited organization having a comprehensive quality system in place assuring constant commitment to excellence. After production of new column set batches, they are tested in accordance with strict internal quality control protocol:
- Out of every 150 newly produced columns one set is examined by QC-dept.
- The recovery rates of all PCDD/Fs and PCBs must be> 70%
- The blank values PCDD / Fs must be <0.5 pg TEQ / column set
- The blank DL-PCBs must be <0.05 pg TEQ / column set
Only if the above requirements are met, a batch passes Miura quality control with a column set certificate of quality.
These certificates contain a report of blank and recovery tests performed and provides corresponding chromatograms.
Column set certificates of quality are provided with every delivery of column sets and can be viewed and downloaded in the download section
