New scheme for laser diffraction particle size analysers
Users of laser diffraction technology are invited to take part in a new proficiency testing scheme launched by LGC Standards, a division of LGC that offers feedback on the accuracy of particle sizing measurements.
The Particle Analysis and Characterisation Quality Scheme (PACQS) is a training tool for laboratory and production personnel carrying out the tests who can seek advice from the major instrument manufacturers that contribute to the independent advisory group.
Elizabeth Jordain, LGC Standards and head of its PT business, said: "PACQS is our evolution of the Laser Diffraction Proficiency Testing Scheme (LDPTS) and it ensures the availability of regular proficiency testing in this important area of quality assurance.
"The scheme will continue to operate in line with the LDPTS protocol and LGC´s bespoke software ´PT Manager´ will enable efficient and timely processing of the results and reporting via the internet, a key factor of the scheme’s value as a powerful training tool for users of particle sizing instrumentation. LGC Standards will continue to grow the scheme, potentially increasing its scale and number of participants, under the new name of PACQS, to be of value to its members as well as the worldwide community of particle analysts."
The scheme runs from September to August with a quarterly distribution of material to laboratories. Laboratories can choose in which distributions to participate and a discount is available to those taking all four rounds. Results are reported at the end of each round within 15 working days.
LGC is a global leader in proficiency testing services to the food, pharmaceutical, beverages, and environmental sectors.
