Quick Tips
What can I do to improve separations in LC-MS?
What can I do to improve separations in LC-MS?
You can use additives such as trifluoroacetic acid or formic acid to improve the resolution. A complete range of high purity LC-MS additives is available in bottles or ampoules.
What solvents should you select for GC-MS analysis?
Typical solvents are hexane and iso-octane. More polar solvents like acetonitrile and toluene can be used, but you probably need to invest more time in the development of the injection method with these solvents.
Another influence is sample pre-treatment, e.g. in what solvent will your extract end up after the last step of the preparation procedure?
What kind of standards are available to calibrate my UV/Visible spectrophotometer?
Different standards in ampoules delivered in kits with a complete certificate of analysis are available to check parameters such as:
- Absorbance control
- Stray light testing
- Resolution power testing
- Wavelength testing
If I order a pH meter, what accessories do I need?
You need a pH electrode and at least two pH buffers, one at pH 7 and the other at pH 4 or 10. Optional accessories that will prolong the life of your electrode include a storage solution, soaker bottles and cleaning solution.
