Comprehensive tool for data analysis in thermal-optical sampling systems.
ASTOS (Automatic System for Thermal-Optical Sampling) is a software program that is used to analyze data collected by thermal-optical sampling systems. These systems are used to measure the composition and properties of atmospheric particles, such as aerosols, in order to understand their impact on climate and air quality.
ASTOS is a powerful and flexible tool that is used to process, analyze, and visualize data from thermal-optical sampling systems. It includes a range of features for data management, analysis, and visualization, and it is designed to be easy to use and user-friendly.
ASTOS is often used in conjunction with other data analysis and visualization tools, and it is widely used in research and scientific applications. It is a valuable tool for understanding the properties and behavior of atmospheric particles, and it is used by a wide range of organizations, including universities, research institutions, and government agencies.

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
