  • Assisting microwave digestion systems with Automation for Associated sample workup tasks

    Microwave-assisted sample digestion techniques excel in decomposing tough samples completely by raising the temperature of reagents higher than the boiling point. The key to increasing the boiling point of reagents is their entrapment in Teflon® lined close digestion vessels. The usual digestion process starts with the samples being weighed in Teflon® liners and digestion reagents added ...

  • Syringe Sampling for Counting Particles in Fluids

    Before measuring particles in fluid, consider the method for delivering the sample fluid to the particle counter. For unpressurized fluid sources, the choices available depend on the sample fluid. Water provides the greatest range of options, while fluorinated chemistries such as HF can significantly restrict the options. Compatibility of the wetted surfaces with the sampling fluids will help you ...

  • How to Select a Portable Airborne-Particle Counter for ISO Certification of Cleanrooms

    Basics Certain factors are routinely considered for any particle counter purchase, such as price, warranty, quality, and expected laser lifetime. When selecting a particle counter for cleanroom certification it is important to consider additional factors. Of these, sensitivity and flowrate are the most important parameters, both of which determine the sampling time required to complete ...

  • Optimized Molecular Contamination Monitoring for Lithography

    Abstract A new approach to monitoring molecular contamination in lithography is presented. Recent technical advances have made it feasible to perform continuous real-time monitoring with significant advances in sensitivity and stability while minimizing sample tubing effects. These improvements are realized by using a small, low-cost monitor that is dedicated to monitoring a single ...

  • Part I: How fast of a sample rate does your data logger need?

    We often receive requests for data logging systems that can sample the inputs 100’s or 1000’s of times a second. And while we offer several different systems that can provide kHz sample rates, we often try to get a better understanding of the application to see if this is really necessary. As you increase the sample rate there are a number of costs that go up quickly. It’s not ...

  • A Complete Guide to Benzene

    Why is Benzene so hazardous? VOCs have a significant vapour pressure at normal ambient temperature which means they evaporate (volatilise) at low temperatures so they can easily enter the body through normal breathing but can also be absorbed through the skin or by swallowing material containing it. The effects on worker’s health depends upon how much benzene they are ...
