ROMIL-TvR Traceable Volumetric Reagents for High Precision Titrimetry

At Last - Traceability in Titrimetry

ROMIL-TvR Traceable Volumetric Reagents for traceable results The typical QC laboratory has long had a responsibility to produce precise and accurate analyses. But with today's business pressures there also comes a requirement for quick production of results within a quality conscious environment. ROMIL-TvR^™ traceable volumetric reagents provide the means to achieve these aims through cost effective products that are traceable to SI units through the unique ROMIL PrimAg^® system.

ROMIL-TvR^™ reagents are available in a wide range of concentrations and in a variety of convenient pack sizes. Supplied ready-to-use they enable the busy analyst to select the optimum pack size for the application. The nominal molarities for the range are, in general, accurate to within 0.1% (factor limit 0.999-1.001) and are equally suitable for both manual and automatic titrators.

A number of 'high accuracy' solutions are available for techniques where the maximum precision is required. These reagents are generally specified with an accuracy ten times greater than the basic reagents and consequently, care is called for in their handling and use in order to attain the maximum accuracy of the final result.

Some reagents are available in concentrated form. Advantages of concentrates include reduced bought-in cost as well as a smaller storage area requirement. They are supplied in 6-packs of vials containing the concentrate together with user instructions and pre-printed labels for the final concentrations. Provided that the instructions for dilution and make up are carefully followed, the resultant solutions will be accurate to ±0.2% of the nominal molarity (factor limit 0.998 - 1.002) and SI traceability will be maintained. Alternatively, calibration (i.e., 'standardisation') of the final solution with a suitable ROMIL PrimAg^® stoichiometric certified reference material will also provide such traceability and may also be used to improve the accuracy.

	Key benefits overview
Traceability to SI units	ROMIL-TvR™ reagents are pre-calibrated in-house within the ROMIL PrimAg^® scheme thereby providing direct traceability to the SI unit, the mole. A major potential source of error - the uncertainty associated with the assay of the material - is thus controlled and significantly reduced.
Ease and flexibility of use	ROMIL-TvR™ reagents are available in a wide range of molarities and pack sizes, offering maximum choice in use. ROMIL-TvR™ concentrates have the flexibility to be diluted to a number of easily and accurately obtained working strengths. The use of a simple pack design to contain the concentrate makes it easy to ensure complete transfer to the volumetric flask.
Cost-effective analysis	ROMIL-TvR™ reagents offer exceptional value for money. A combination of attractive pricing with defined traceability results in the highest cost to performance ratio commercially available today.
