Fluka Solvents for HPLC

In liquid chromatography the quality and reproducibility of the separation depends not only on the properties of the stationary phase, but decisively on the quality of the solvents used.

Fluka has been optimized all HPLC solvents for liquid chromatography applications. HPLC solvents are lot-tested and precisely controlled to meet the high quality requirements of successful HPLC separations:

  • Low UV-absorbance, assuring optimum sensitivity
  • Guaranteed suitability for fluorescence detection
  • Controlled low content of non-volatile components like water, free acid and free alkali, assuring long pump-seal life
  • Low particulates, pre-filtration is not necessary
  • High assay, assuring high purity

Gradient grade HPLC solvents are specified with a gradient elution test to illustrate the interference-free baselines. Both UV absorbance and fluorescence signals are monitored.
All HPLC solvents are delivered with an expiration date.

Concept of High-Purity Solvents for HPLC

In high performance liquid chromatography the quality and reproducibility of the separation depends not only on the properties of the stationary phase, but decisively on the quality of the solvents used. The solvent line CHROMASOLV® offers guaranteed quality specially tailored to chromatographic requirements, in conjunction with batch consistency. Please find below the different product groups with description and detailed product lists.



G CHROMASOLV® solvents for gradient elution
CHROMASOLV® solvents for HPLC
E CHROMASOLV® solvents for HPLC
The G CHROMASOLV® qualities were developed for sensitive gradient elutions at short wavelengths and with very high requirements with regard to UV-transmittance and fluorescence detection. The CHROMASOLV® solvents are characterized by high UV-transmittance, consistently gradient testing for interfering peaks and base line drift, guaranteed suitability for fluorescence detection, low non-volatile components, free acid and free alkali and an exactly defined low water content. This quality is suitable for measurements in the low wavelength range and has also been tested for suitability for gradient applications and for fluorescence detection.


P CHROMASOLV® solvents for preparative LC
R CHROMASOLV® solvents for routine measurements in LC
The specifications of the
P CHROMASOLV® qualities are tailored fully to the requirements of preparative liquid chromatography. In particular this means low contents of non-volatile impurities and of free alkali.
This quality is available for routine analysis in which chromatography is not carried out with gradient elution at short wavelengths. It is suitable for isocratic analysis, for example at 210 nm or with gradients at 254 nm.

Concept of LC-MS CHROMASOLV® Solvents for LC-MS Analysis

IMPROVE STABILITY OF LC-MS BASELINES BY USING HIGH-QUALITY SOLVENTS

Using LC-MS CHROMASOLV® eliminates impurities and the need to lot-select your solvents.

LC-MS is fast becoming the dominant analytical tool for researchers in a wide range of industries and application areas. LC-MS combines the advantages of a chromatographic separation with mass detection by MS. Low detection limits and qualified analysis of molecular structures brought this application a new and growing popularity especially in the field of biotechnology and within the R&D departments of the pharmaceutical industry.

Besides the column and instrument, the solvent can seriously affect the performance of an LC-MS system. Impurities arising from the solvent can mask low levels of target ions, or give false peaks, resulting in faulty interpretation of spectra. Sigma-Aldrich's Riedel-de Haën brand of LC-MS CHROMASOLV solvents is manufactured specifically to meet the needs of modern LC-MS instruments because they are designed to have low contents (max. 100 ppb) of alkaline impurities, such as calcium, magnesium, potassium and sodium, which can form clusters with the analyte, especially when using electro spray ionization. All LC-MS CHROMASOLV solvents undergo a battery of specific UV-spectroscopic quality control tests to guarantee the traditional Riedel-de Haën CHROMASOLV specifications and to ensure the reproducibility. They are also checked for LC-MS use by a special test and for particles, which could clog up Nano-LC inlet filters.

LC-MS CHROMASOLV® - Solvent Blends

LC-MS blends
LC-MS allows the detection and quantification of many analytes. The minimisation of artefacts requires very well specified solvents spiked with ultra pure salts and acids. These additives are used to improve the chromatographic peak shape and to optimise ionisation in the MS interface. The most commonly used solvents in LC-MS techniques are acetonitrile, methanol and water. Additives can include trifluoracetic acid, formic acid, acetic acid and ammonium acetate.

LC-NMR CHROMASOLV® Solvents for LC-NMR Analysis

Although an efficient separation method is available by HPLC, no structure determination is possible when detecting separated compounds by UV-detector. Thus NMR spectroscopy is a better universial detection method. A combination of both methods was evident and LC-NMR was born.
Solvents that meet the high requirements of HPLC and proton NMR are needed. But the high throughput of solvents in HPLC does not allow the usage of expensive deuterated solvents as usually required for NMR. HPLC Acetonitrile is often contaminated with impurities containing protons such as propionitrile which is no problem in UV but NMR detection. Therefore a dramatic decrease of proton containing contaminants for LC-NMR solvents is essential.
Acetonitrile LC-NMR CHROMASOLV® (34955) from Riedel-de Haën is the solvent of choice. It was developed to obtain the superior specifications required for LC-NMR. There are no further signals in 1H-NMR that exceed the size of methyl signals (more than 5% at 3.78 ppm NMR of 0.0006% trimethoxybenzene) at typical LC-NMR conditions.
