Liquid chromatography paired with mass spectrometry (LC‑MS) is an extremely sensitive technique and therefore requires solvents and eluants of the ultimate purity. ROMIL‑UpS™ ultra lc products are purified to meet the stringent criteria demanded by analysts. Product is filled into bottles which have been specially pre-treated to ensure that trace metal impurities are kept as low as when freshly manufactured which avoids problematic adduct formation.
ROMIL‑UpS™ ultra lc solvents are compatible with ESI/APCI ionisation methods in both positive and negative modes. Additionally, their low ionic background resulting in low ion suppression make ROMIL‑UpS™ solvents the ultimate choice.
Furthermore, the coupling of liquid chromatography with ICP‑MS (LC‑ICP‑MS) offers many advantages for speciation analysis. With background ionic impurities controlled to low ppb levels, ROMIL‑UpS™ ultra lc solvents are eminently suited to this triple hyphenated technique.
Likewise, eluants for hyphenated chromatography techniques demand the maximum performance from the constituents. LC‑MS in particular requires the use of the highest purities available in order to maximise its analytical potential.
ROMIL-UpS™ ultra purity eluants are formulated from our ultra purity solvents. Combining a very clean UV transmission profile with extremely low fluorescence background, ROMIL-UpS™ ultra purity solvents and eluants achieve the high ionisation efficiencies that ensure a reproducible and consistent analytical performance.
