The Ultimate Quality for Hyphenated Techniques Whilst the purity levels of ROMIL-SpS™ solvents are suitable for most instrumental applications there are some high-sensitivity techniques which demand even greater purity. Analytical instrumentation can now detect substances at such low concentrations that were previously considered undetectable. This is especially true in environmental analysis where detection of trace amounts of pollutants is now the routine. Hyphenated techniques in particular place a great burden on the purity of the solvents. These double or triple detection systems require a solvent quality matched to the requirements of all the configured detectors. ROMIL-UpS™ Ultra Purity Solvents have been developed to address this requirement. Purification techniques are more exacting and each batch is carefully use-tested to ensure the best possible performance. Not only is the original purity controlled but also the actual purity when opened some time later. This is done by selection of suitable raw material, purification process and shelf life of final product based on many years experience as the acknowledged leader in this field. Because no
matter how pure the solvent, it will eventually degrade
over time. Such degradation products may become apparent
during use, either as additional peaks, or through
unwanted and unexpected reaction with the sample. At
ROMIL we have found that the purer the solvent starts out
the longer its useful 'stability'. Selection of an
appropriate stabiliser, as in dichloromethane, can also
enhance such stability. Our expertise is distilled into
every bottle of ROMIL-UpS™ solvent which
means a greater assurance of quality results, first time,
every time. |
