Coreolis versus real time flow monitoring

We are sometimes asked about the benefits of TESTA’s liquid chromatography flowmeter compared to Coreolis flow devices? Critically our unit offers immediate reading while Coreolis devices typically need 30 seconds or more to stabilise before readings can be considered 'ok'. This long- and variable-time lag with Coreolis devices introduces uncertainty into trusting your flow measurements. Additionally, the time resolution of the TESTA flowmeter is forty-five milliseconds compared to several seconds with a Coreolis device. The low resolution of Coreolis devices means they not suitable for troubleshooting flow problems with your chromatography system which are typically fast processes.

Detection of air bubbles in semiconductor manufacturing processes can negatively affect your product quality and production efficiency. For example, the presence of air bubbles in the photoresist used in photo lithography can result in defective wafers. In addition, the presence of air bubbles in semiconductor wafer manufacturing process coolant may lead to an interruption of the process and lower production efficiency. Designed to help solve such problems, the Solvent Line Monitor (SLM) is a programmable, high sensitivity device for automated detection of gas bubbles in liquids.

Automated detection of empty HPLC system solvent reservoirs

While many modern HPLC and uHPLC instruments offer facility to detect empty solvent reservoirs, they also require human intervention to inform the system about the status of solvent feed bottles. Dedicating a technician to such a mundane task is poor use of resources and limits HPLC system running time to standard lab hours.

Cleaning liquids play a key role in the production of #semiconductor wafers. #Preciseflowmeasurement is critical to ensure that exactly the right amount of #cleaningsolution is used. Too little and the cleaning process must be repeated or worse you risk valuable wafers having to be discarded. Likewise, using too much cleaning solution increases your costs. Built from inert materials, our #LiquidFlowmeter is the perfect real-time non-invasive measurement for this critical application.
