Subject Matter Experts

From our core business of providing scientific solutions to our clients, we have developed innovative products. Some are produced internally, and some have arisen from partnerships with other research organizations. 

For example, we build lab software solutions to help manage and streamline your labs data, and environmental testing products for a variety of applications. 

  • IntelliSEM is a powerful automated particle analysis system.
  • ParticleID is  a customizable cloud hosted web application used to identify foreign particulate matter and  assist with root cause investigations. 

Other products we create count particles and help keep the air and environment safe.

RJ Lee Group is a materials analysis laboratory and consulting company which serves many different industries. We offer scientific solutions such as industrial forensics services, laboratory and testing services, litigation support, and laboratory software to many industries:

Laboratory for Air Sampling and Analysis

Air Toxics Sampling and Analysis

RJ Lee Group has a long history of working with industrial facilities to help control air toxics emissions. We provide practical solutions for monitoring, sampling, and emissions analysis.

RJ Lee Group also performs environmental site assessments and source apportionment plans to determine the contributions of various pollution sources to a location of interest. Our tests fully comply with EPA standards, including:

  • Air Sampling and Testing capabilities using Method TO-15
  • Air Sampling and Testing capabilities using Method TO-17
  • Air Sampling and Testing capabilities using Method TO-11, as well as other Industrial Hygiene Methods

Determination of Volatile Organic Compounds (VOCs) in Air: TO-15 and TO-17 Methods for VOCs

Human health may be affected by VOCs in both ambient and indoor air, so monitoring must be done quickly, efficiently and accurately. When you need to monitor to comply with industry safety standards or government regulations, the PTR-MS mobile laboratory system will give real-time quantitative results down to the pptv-level. Whether you are sampling indoor air quality (IAQ) proactively to identify and prevent issues that may become legal or safety concerns, or to monitor for trend logging over a period of time to ensure compliance, the PTR-MS can provide a solution.
