Standard Methods for Examination of Water and Wastewater at Particle Technology Labs

The water industry is one of many industries that relies on PTL for important scientific data. Flood studies, filter determination, and verifying compliance with water quality standards are just a few ways that water analysis results are utilized. Our most popular techniques for water analyses include Single Particle Optical Sensing (SPOS) / Light Obscuration and Nanoparticle Tracking Analysis.

Particle Technology Labs' Elizabeth Fitzgerald Gives Presentation in Amsterdam

Particle Technology Labs' Particle Chemist III / Team Leader Elizabeth Fitzgerald just returned from the Netherlands where she was one of three presenters at The Center for Professional Advancement's course entitled, Powders: Their Properties and Processing. The three-day event took place December 9th through December 11th, 2019, in Amsterdam.

The primary purpose of the course was to "review the various properties of powdered solids pertinent to the development and manufacture of the products of the pharmaceutical, cosmetic and allied industries." While the course was designed for those in product development, the event was attended by scientists, suppliers and technologists.

During the three-day course, Ms. Fitzgerald presented on the following topics:

In her first session, Characterization of Powder Particle Size, Shape, Flowability and Density, Ms. Fitzgerald discussed particle size basics, particle sizing techniques, powder flowability and powder densities.

In her second session, Fine Particle Characterization: Dynamic Light Scattering (DLS), Nanoparticle Tracking Analysis (NTA) and Zeta Potential, she discussed fine particles, Brownian Motion, and the latest techniques for fine particle characterization.

In her third and final session, Characterization of a Particle's Surface and Pores, she discussed surface area determination, pore size and distribution measurement, and surface texture measurement.

Elizabeth Fitzgerald joined PTL as a Particle Characterization Chemist I in 2014, before eventually advancing to her current position as Particle Characterization Chemist III, and Team Leader in the Laser Diffraction department. Ms. Fitzgerald works closely with PTL clients and chemists to ensure the highest degree of analytical integrity, with a specific focus on laser diffraction techniques and instrumentation. Her current responsibilities include test method development and instrument qualifications. She is also actively engaged in laboratory training, assisting with the implementation of safety programs and procedures.

The Center for Professional Advancement - CfPA is the largest accredited technical training organization in the world offering technical training and continuing professional education courses to those in the pharmaceutical, biotechnology, medical device, chemical engineering and cosmetics industries.

PTL ISO/IEC 17025:2017 Accreditation Complete

Particle Technology Labs, the premier particle characterization service laboratory and advisory company is pleased to announce a change in accreditation status from ISO/IEC 17025:2005 to the most updated ISO/IEC 17025:2017 criteria. From the website, “In order to reflect the latest changes in market conditions and technology, the new edition of the standard encompasses the activities and new ways of working of laboratories today. It covers technical changes, vocabulary and developments in IT techniques and takes into consideration the latest version of ISO 9001 on quality management.”
ISO/IEC 17025 is an internationally recognized quality standard for calibration and testing laboratories. Accreditation to this standard asserts that the laboratory is competent to conduct specific testing as detailed on the certificate of accreditation. For an organization to be ISO 17025 accredited, its facility must undergo a rigorous independent assessment which evaluates the quality management system, training practices, testing programs, and instrument maintenance processes.
This accreditation assures PTL customers that laboratory operations, personnel training, equipment calibration, maintenance, and operation and quality assurance systems are in compliance with ISO/IEC 17025:2017 requirements.
“Particle Technology Labs is dedicated to providing the highest quality service to our customers. One way that we do this is to continually improve and build upon our laboratory practices and quality systems. Securing this accreditation is only a part of the commitment that we keep to our customers, providing the best value and highest standards in particle characterization services.”
