Exploring the pitfalls of Flow Chemistry – industry and academic insight
Recently, H.E.L invited four specialist flow chemistry practitioners to speak at an online symposium on the topic. After the speakers had shared their research and experiences and answered questions from delegates, we took the opportunity to ask some questions of our own. Here, our speakers share their own ‘pain points’ of working in flow.
Getting the best from your vent sizing experiments
Dr. Roderick McIntosh shares his top tips for making sure that vent sizing experiments at the laboratory scale give you the information needed at the production scale….. read More
In our second part on battery testing (2019/2020), we highlight the unique applications that our customers use on our equipment. Its always great to see this work get the recognition it deserves from its peers …….read more
A question that often crops up is what testing is best? Should we perform high Phi-factor or low Phi-factor tests? Is one better than the other?
As is often the case, there is no straightforward answer and it will depend on the desired …….read more
We’ve been doing some literature research and have found a few interesting recent (2019/2020)
publications looking at battery testing. We’ve shared four of the most relevant ones here and……..read more
Real-time, on-line analysis of exhaust CO2 and O2 from your fermentation process provide a wealth of information to help you understand and control your fermentation process.
These are presented two case studies of the use of off the Tandem gas analyzer in fermentation process development.
Test pre-preparation–Why you should evaluate your sample before testing
After my previous post regarding loading a test cell, I am reminded of the time I had to manually inject caustic soda (sodium hydroxide – NaOH) into hydrogen peroxide (H2O2). I charged the peroxide into the Phi-TEC II test cell and then started a “closed-cell” test. This style of testing allows for heating and temperature control to start before the two reagents are mixed. When the test conditions were ready, I carefully put a……….read more
Over spring and summer 2020, two leaders for major geographies joined H.E.L. In March, Qing (Steven) Chen took on leadership for the H.E.L business in China. Then, in June, Mert Sahin took on a similar role for our North American business. Now that they’ve had some opportunity to settle into their roles, our C.M.O Paul Orange caught up with them and got their thoughts on……….read more
So, we’ve all been there. You have a new sample that you need to test on a Phi-TEC II, and you need to get the sample into the test cell. But wait a minute, here we have a solid sample, and a 1/8” feed line. Or perhaps you have a reaction mix that starts reacting immediately.
What do you do? How do you get around this?……read more
