TSI's Aerosol Conditioning Systems are designed to ensure that instruments are provided with clean and dry air to maximize measurement accuracy and repeatability.
Aerosol Diluters are essential items needed in combination with many of TSI's particle sizing and counting instruments for a wide array of measurement applications.
At TSI, we manufacture a full line of individual aerosol generators and dispersers capable of producing monodisperse or polydisperse aerosols depending on your application.
TSI Aerosol Monitors offer real-time, direct-reading results, which is quickly becoming an industry best practice in occupational hygiene, indoor air quality, and outdoor environmental fugitive emissions monitoring.
Aerosol neutralizers are an essential piece of many aerosol research studies because aerosol particles dispersed by nebulization, combustion, or powder dispersion are usually electrostatically charged.
TSI’s Continuous Monitoring Systems provide a complete solution to monitor your cleanrooms. FMS Facility Monitoring Software is the backbone of a fully compliant facility monitoring system coupled with AeroTrak Remote Particle Counters and other environmental sensors to create a robust clean room monitoring system.

PolyMax™ Plastics Analyzer changes the game in plastics identification, using laser-based technology to validate the chemistry of both light and dark plastic compounds — based on science, not best guesses.
TSI's portable, battery-operated primary calibrators are lightweight and easy to use. Volumetric flow rate is displayed continuously so adjustments to pump flow can be made in real-time.
From quantitative fit testing equipment to mask integrity testing equipment, TSI has respirator fit testing solutions to comply with regulated standards and help ensure your respiratory safety.
TSI provides room pressure monitors and controllers for a variety of critical environment applications including hospital isolation rooms, laboratories, and cleanrooms.
TSI's full line of industrial ventilation test instruments are designed to accurately and reliably measure a wide variety of parameters important in monitoring and maintaining indoor environments.
TSI Ventilator Test Systems measure flow, pressure, and multiple parameters of ventilator performance with high accuracy.
Airflow™ Instruments are accurate, high quality, professional-grade instruments used by a wide range of customers, including building service contractors, commissioning specialists, facility engineers and research professionals.
TSI manufactures high-quality Alnor® air velocity equipment. The Alnor brand of handheld instruments is widely used by HVAC contractors, facility personnel, building engineers, safety officers and industrial hygienists worldwide.
A family of chemical analysis solutions from TSI including LIBS and Raman Spectrometers.
ES-SMPS and ES-DMA (a.k.a. macroIMSTM Macroion Mobility Spectrometer, GEMMA, ES-IMS, nES‑GEMMA) are acronyms coined by researchers to describe an Electrospray Aerosol Generator (EAG) paired with a Scanning Mobility Particle (SMPS) Spectrometer used to perform rapid, high resolution sizing of nanoparticle colloids, proteins and other macromolecules.
The fundamental measurement behind the ES-SMPS technique is Differential Mobility Analysis. Briefly described, the EAG is used to aerosolize the colloidal suspension (similar to ESI-MS), and then particles are sized via their electrical mobility (ability to traverse an electric field) resulting in a measurement of electrical mobility diameter (EMD) which is a fundamental function of particle size.
The ES-SMPS technique is frequently chosen by researchers over more conventional techniques and its use is increasingly widespread. The National Institute of Standards and Technology (NIST) & the National Characterization Laboratory (NCL) issued a Joint Assay Protocol, “PCC-10: Analysis of Gold Nanoparticle by Electrospray Differential Mobility Analysis (ES-DMA)” which details a protocol for size analysis of liquid born gold nanoparticles via ES-SMPS.
