How to know whether your UV/VIS Verification methods conform to USP 857 Standards

The United States Pharmacopeial Convention 857 or USP 857 necessitates that all equipment imported into the USA by pharmaceutical companies in the country should mandatorily satisfy their set of requirements. This mandate was established and brought into play on 1st May 2016 and continues to affect all vendors in this field of operation.

The USP 857 standards contain very specific criteria for verification of wavelength accuracy and photometric accuracy of concerned equipments. There are also new requirements suggested for spectral resolutions and stray light which wasn't present previously. Apart from this, they have also laid out very specific requirements for filters for each verification that is conducted. These USP requirements are more in tandem with International Pharmacopeial requirements. All new and existing laboratories in the USA are expected to conform to these new set standards and actively involve in testing these changes which are now recognized officially.


The measurements obtained should be suitable in terms of precision, accuracy, linearity, range, robustness, quantitation limits, specificity and detection. The quality of your test results using laboratory equipment is deemed to be satisfactory and accurate, only if they meet these conditions. Nevertheless, it is also essential to consider other factors like properly planned analytical methods, trained analysts, error-free experimental setups and performance level of the system under consideration to ensure quality and accuracy of test results.

Difference between previous USP Standards and USP 857 and its implications

The original USP guidelines did not set out specific guidelines with regard to laboratory operations and techniques, although it did suggest general principles. The current revision addresses all these relevant factors and provides a very thorough and specific format for testing and verification of all the guidelines, that all companies are expected to adhere to.

Impact of this on your test results and lab operations

USP qualification kits allow you to check for compliance with USP 857 criteria. These kits contain all the required reference materials, so suitable parameter verification can be carried out effectively and on-time.

Conforming to the currently set out standards will ensure that all labs will have a uniform concept and follow a common format, that eliminates chances of error. Consistency in the approach will improve use and help to create a uniform standard across the industry. This will establish reasonable and meaningful standards in the long run which are scientifically sound and appropriately acceptable for the given conditions.

To verify the absorbance obtained by your spectrophotometer use Hellma Certified Reference Material from FirstSource Laboratory Solutions.

Care of Spectrophotometer Cells

Cells or cuvettes are optical instruments used in the spectroscopy. These cells are manufactured with great skill, uniformity, and maintain high quality standards. Hellma is dedicated to meet the requirements and maintain the standards. Cell and other related components pass through various inspection procedures. The raw materials also undergo certification before the manufacture and packaging of these optical cells. It has been observed that general use of cells lead to gradual degradation of precision surfaces. In spectroscopy, it is very important to have a good optical cell as it helps in providing accurate results. There are different types of solvents which mainly affect the optical cells. The use of high alkaline as well as high acidic solvent fastens the degradation of hardest glass as well as quartz cuvette. The inefficient cleaning or mishandling of these optical cells can also lead to result inaccuracy and related complaints. Hellma uses borosilicate and fus...

Features Of Analytical Balances That Can Be Used For Research Purposes

A scientific research environment needs absolute precision.   These research activities require absolute and accurate measurements of different factors such as temperature, timing and weight. The use of modern technology in manufacturing various testers and measurement devices have led to authentic products like analytical weighing scales, digital thermometers and other measuring instruments that give precise and absolute readings. Analytical balances are the sought-after devices for scientific research purposes. These balances are very accurate and show readings up to seven decimal places. Such accurate readings are very essential for success of an experiment. Along with being accurate, analytical balances are also functional. These balances are able to read the weight of the samples and show minor dispersions on the scale platforms as well. The most important feature of RADWAG analytical balance is its zeroing capability. An ideal balance should take less than five s...
