Three Things Your Particle Size Contract Lab Needs to Know to Match Your Specifications

By Jorie Kassel, Laboratory Division Manger

Particle size specifications are designed to ensure raw ingredients and products perform as expected. Often, companies are required to verify that their material is meeting these specifications regardless of which supplier is used. Using a contract lab for this purpose is very common but not always straightforward. There are many techniques to determine particle size and the methodology used may be open to interpretation when reviewing a material specification sheet.

The experts at Particle Technology Labs have years of experience working as a third-party quality control laboratory with many diverse technologies in-house. We can help guide you in your quest to confirm your material is being produced to the desired specifications.

Through-Pore Galore: Face Masks, Filters, and More!

By Chorthip Peeraphatdit – Particle Characterization Chemist IV / Team Leader

You don’t have to be a scientist to appreciate the importance of filtration in our world today. Face masks and air filtration systems have been employed for protection against a pathogen in a pandemic and against harmful particulates from a forest fire or pollution. The filtration action by face masks and other filtration media might be achieved by a combination of various factors, one of which is the size exclusion effect or sieving action. This simply means the things you do not want (e.g. aerosols, dust particles) should be too big to pass through the openings (pore channels) in the filter media. Today we will take a deeper dive into characterization of the size of pore channels in filter media.

What Is Method Validation and Might You Need It?

By Shane Hill

Confidence, reliability—ultimately peace of mind. In short, this is the takeaway following an analytical test method validation.

Do you work in pharmaceuticals, cosmetics, or the environmental realm? All of these fields, and more, benefit greatly from the method validation process. While initially only a mused measure proposed by minds at the US Food & Drug Administration to enhance the integrity of pharmaceutical drugs in the 1970s, it rapidly became a codified and collective effort to improve general processes in manufacturing. Supply chain elements such as product filling and equipment sterilization caught immediate attention and were subjected to a validation metric whereby consistency of execution was paramount. Soon after manufacturing yields were tightened and made more reliable, the eyes at FDA deemed the validation process applicable to the granular level of characteristic tests for sample analysis techniques such as particle size distribution.

Test validation began to incorporate elements from the engineering world, such as the concept of “gauge R&R,” or more broadly termed, a gauge repeatability and reproducibility systems approach. In equipment design, being able to repeat a blueprint within tight specification and moreover reproduce it at another manufacture site was crucial. This same concept was extended to sample material testing in a wide variety of applications.

Using Image Analysis Testing for Particle Characterization

Using Image Analysis to Answer Your Most Challenging Particle Characterization Questions

By Michael Vinakos

The possibilities are endless when it comes to image analysis. Over the years, the experts at Particle Technology Labs have developed and validated countless particle characterization methods using microscopic image analysis, and the wealth of information from these tests is unmatched for characterizing particle systems..

Our Roots as Experts in PM10 and PM2.5 Testing

By William Kopesky – Director of Analytical Services

Did you know Particle Technology Labs began as a testing service for companies needing to meet EPA environmental safety standards? While we are most known today for our testing for the pharmaceutical industry and our commitment to cGMP quality assurance regulations, some will be surprised to learn that the company’s early services were in testing environmental emission and water filtration samples. Now, almost 30 years later, we still assist companies in these industries including some of those first clients who are still with us today!

Testing for PM10 and PM2.5

The founder of Particle Technology Labs, Richard Karuhn Sr., started the company by providing analysis of stack emission samples for PM10 and PM2.5 in 1992. He not only tested them – he spent time collecting them as well!

What do PM10 and PM2.5 stand for? Glad you asked. PM is an abbreviation for “particulate matter.”  PM10 or PM2.5 is the particulate matter in an emission sample that is less than 10 or 2.5 micrometers respectively by mass. These sizes are of interest to the USA Environmental Protection Agency (EPA) as particles in this size range are not easily filtered out by the nasal passages nor impact the back of the throat for removal when we breathe. Particles less than 10 micrometers will enter the lungs and can cause both acute and chronic respiratory issues. Factories, power plants, and similar types of companies are required to monitor and control their emissions for these particles or risk expensive fines and/or production shutdowns.
