Top 6 Questions You Should Ask When Buying a system for chromatography analysis sample prep
1. Can this system perform exhaustive extractions in about 10 minutes?
2. Can this extraction system operate unattended overnight?
3. Does the system change solvents and perform rinses automatically between samples?
4. Does the extraction system comply with U.S. EPA methods?
5. How does solvent consumption compare to other systems?
6. Can the extraction system handle solid and semisolid and samples, or are multiple systems needed?
The range of chromatographic approaches spans from paper chromatography to ultra-high-pressure liquid chromatography. Consequently, the sample preparation varies as much as the technique. Nonetheless, a few trends apply to this diverse field, including microsampling. When looking at sample prep products, users will want to consider the method of chromatography and then add the detection, such as UV or triple-quad mass spec. The characteristics of the user’s samples are also important in deciding what products to buy; and online tools can be useful in choosing products and equipment, based on the compound.
Time spent per month on the following sample processes for chromatography analysis in our reader’s labs, based on our latest survey:
| Collection of samples | Sample preparation | Storing of samples | Sample analysis | Data management | |
| Less than a day | 46% | 23% | 37% | 14% | 19% |
| 1 - 5 days | 29% | 37% | 34% | 37% | 44% |
| 6 - 15 days | 14% | 22% | 11% | 25% | 21% |
| 16 - 25 days | 3% | 9% | 4% | 13% | 6% |
| 26 - 30 days | 8% | 8% | 13% | 11% | 10% |
The number of samples our respondents process per month for chromatography analysis. Of those respondents whose labs send samples out for analysis, close to 50 percent do so because they don’t have in-house technology available for the analysis; 20 percent require confirmation of their analysis; and 14 percent are required by regulation.
| Number of samples processed per month for chromatography analysis | Total samples processed | Samples processed in-house | Samples sent out for Processing |
| 1-25 | 48% | 31% | 69% |
| 26-100 | 23% | 74% | 26% |
| 101-250 | 10% | 87% | 13% |
| 251-500 | 7% | 93% | 7% |
| 501-1000 | 5% | 95% | 5% |
| >1001 | 7% | 96% | 4% |
