Fluorescence Spectrometry

Fluorescence Spectrometry A very low fluorescence background makes ROMIL‑SpS ™ super purity solvents suitable for this useful technique as well as fluorescence detection in HPLC. Test for Fluorescence Spectrometry: Fluo...

Gas Chromatography

Gas Chromatography Low non-volatile residue levels due to glass distillation make ROMIL‑SpS ™ super purity solvents suitable for simple analysis of pesticide and other extraction residues. The solvent may be concentrated by ...

Gas Chromatography-Mass Spectrometry

Gas Chromatography-Mass Spectrometry The pairing of gas chromatography with mass spectrometry (GC‑MS) results in a specific and sensitive technique for identifying and quantifying a wide range of relatively low molecular weight c...

General Chemistry

General Chemistry Underlying the advanced analytical techniques in the modern chemical laboratory is general chemistry. As a subject in chemical education it concentrates on the basic knowledge and skills that all chemists need....

High Performance Liquid Chromatography

High Performance Liquid Chromatography High chemical purity together with low water, acidity and residue levels lead to better separations and longer column life with ROMIL‑SpS ™ super purity solvents. Excellent optical puri...

Infra-Red Spectrometry

Infra-Red Spectrometry Clear infra-red windows in many ROMIL‑SpS ™ super purity solvents give a wide choice of suitable solvents. Test for Infra-Red Spectrometry: An infra-red spectrum is matched against that of a refere...

Karl Fischer

Karl Fischer Karl Fischer reagents have been used for water determination in analytical laboratories for more than half a century. The original formulation, being based on pyridine became out of favour during the past 30 years du...

Liquid Chromatography-Mass Spectrometry

Liquid Chromatography-Mass Spectrometry 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 ...

Molecular Biology

Molecular Biology Some of the high purity requirements for solvents in molecular biology are similar to those for HPLC such as transparent UV and low water and residue levels. Thus many ROMIL‑SpS ™ super purity solvents are ...

Organic Synthesis

Organic Synthesis Many organic and organometallic synthetic methods specify a dry solvent as the reaction medium. The exceptional dryness exhibited by ROMIL‑SpS ™ super purity solvents allows synthetic chemists to avoid the ...

Preparative High Performance Liquid Chromatography

Preparative High Performance Liquid Chromatography In contrast to analytical HPLC, preparative HPLC separates and refines compounds following chemical synthesis or extraction from natural sources. In separating such compounds to...

Process Chemistry

Process Chemistry Process chemistry is concerned with the development and optimisation of a synthetic scheme and manufacturing plant procedure for production of high value products such as pharmaceuticals and speciality inorganic...

UV-Visible Spectrometry

UV-Visible Spectrometry Excellent optical purity with a smooth spectral curve renders ROMIL‑SpS ™ super purity solvents suitable for all UV applications. For work at short wavelengths we recommend that the solvent is nitro...

When referring to percent solutions what does %w/w, %w/v and %v/v mean?

Percentage weight for weight - %w/w This means the percent by weight of solute in the total weight of solution. Percent here is the number of grams of solute in 100 grams of solution. For example, a 10% w/w solution of sodium chloride would be mad...

New Interactive Website Launches

We're proud to announce the launch of our new website, an easy-to-use, interactive resource for laboratory professionals requiring high purity solvents, acids, reagents and reference materials. This user-friendly, comprehensive reference site has been redesigned from the ground up and optimised for PCs, tablets and smartphones...

Rebrand for Ultra Purity Products

We’ve re-branded our ultra purity ranges with a new label layout and colour. Purple has long been associated with the highest level of attainment; it represents royalty, imagination, wisdom, creativity and the future. It is the natural choice to denote our highest level of chemical purity, ROMIL Ultra Purity.
