Description

The development of active pharmaceutical components, measurement of contaminants, testing for solubility, and measurement of nucleic acids and proteins in pharmaceutical development all use the well-established analytical technique of UV-Visible spectroscopy. UV standards for USP and EP have been established, and holmium oxide solution has been calibrated for wavelength accuracy from 241 nm to 641 nm. Photometric accuracy, calibrated 60 mg/L, 80 mg/L and 140 mg/L potassium dichromate with blank UV absorbance accuracy to 2A. Potassium chloride, sodium iodide, and sodium nitrate are stray light recognised substances. For testing resolution (spectral bandwidth), use a solution of resolutioncertified toluene in hexane with a hexane blank.

Photometric (Absorbance) accuracy - the accuracy of a systems is absorbance measurement across its intended operational range must be confirmed for the required wavelength and absorbance ranges. Operational Range is the absorbance range that you use to measure samples in your lab at wavelengths close to those used to measure the samples.

Mercury lamp options for wavelength accuracy comparing mercury vapor lamps to other standards used in photovoltaic testing, there are many advantages. These lamps emit extremely well-characterized, unchanging atomic emission lines. The emission lines from low pressure mercury lamps are all produced at the same exact wavelengths. Other standards, such as holmium oxide solutions, are calibrated using the emission spectra of mercury vapor, and a mercury lamp never needs to be re-calibrated.

Control of wavelength accuracy the UV-Vis spectrum's wavelength axis must be accurate (correct and within acceptable limitations) across the intended operational range, according to the wavelength accuracy test. It is advised to test the wavelength accuracy using atomic line spectra from xenon or deuterium light sources. It is possible to utilize rare earth oxides that produce well-characterized absorption bands so that the UV-Vis spectrophotometer wavelength readings can be compared to measured value. Thermo Scientifics multiskan sky high micro plate spectrophotometer is a UV/Vis microplate spectrophotometer that was created to be practical and simple to use for practically any photometric research application, particularly DNA, RNA, and protein analysis as well as turbidity measurements. Because the emission lines generated by a discharge lamp are indicative of the source element and serve as a fundamental physical standard, this procedure is referred to as the primary application. The wavelengths of these emission lines have been measured with an uncertainty of not more than 0.01 nm.

Selecting the evolution UV-Visible model- the 1.0 nm of spectral bandwidth of the Evolution 201 spectrophotometer allows for the collection of high-resolution data for routine quality control and applications in basic research. The Evolution 220 spectrophotometer increases a system's adaptability by offering a configurable frequency options for a wider range of applications. This model has an applications focused beam shape that is designed to work with microcells, diffuse transmittance/ reflectance sphere accessories, and fiber optic probe. The Evolution 260 Bio spectrophotometer brings the ease of preprogrammed bio applications to the Evolution 220 platform for greater efficiency in your life science lab. A high-performance variant with parallel beam architecture and an extra-large sample box for additional accessory options is the Evolution 350 spectrophotometer. For enabling pharmacopoeia wavelength and bandwidth accuracy testing, this model has a mercury lamp option.
