PTL is the leading particle characterization research and advisory company in the United States. We work with major organizations across the private, public and scientific research sectors. Our scope, and expansive knowledge of particle technology allows us to address problems that no one else can, and provide insight and perspective necessary for our clients to make the right decisions. We have deep functional expertise in industrial sectors such as pharmaceutical, environmental, petroleum-chemical,  beauty and cosmetics, manufacturing, and food and beverage. We are the recognized leader in particle characterizations, providing our clients with a broad range of expert services in particle size and count distribution, surface area and image analysis, thermal analysis, powder flowability, and method development, verification, and validation.

Analytical Integrity

PTL provides only the most scientifically reliable and accurate particle characterization test results. Our expert analysts are as qualified and precise as the equipment we use to determine particle size, thermal analysis, powder rheology and more.

The Independent Perspective

A PTL particle characterization test is free of all bias. Test instrumentation is always selected on the basis of merit, never due to business relationships with vendors. Our staff designs all tests and selects from our wide range of instruments with one goal in mind: accurate, independent particle characterization test results.
