Bill Clinton and George W Bush both promised to 'focus like a laser' on the economy. I'll leave the politics to others and focus like a lens on the lack of scientific rigor for this turn of phrase. At risk of appearing pedantic, I have to point out that lasers aren’t actually focused at all. In fact, collimation (parallelism) is one of the characteristics of laser light that make it unique and useful. Lenses are required to focus laser light. You may ask yourself, “So what? It’s a minor exploitation of poetic license.” I agree, but I needed an entrée suitable for...

Polymicro Technologies (a division of Molex) was the first company to mass produce fused silica capillary for the entire capillary gas chromatography market. That was thirty years ago and they are still the single largest manufacturer of the materials. (Polyimide coated, fused silica capillary for GC columns was an HP invention, but they reserved their production for themselves, alone.) Polymicro has made more GC capillary than anyone on the planet, by far: they are considered the experts and they are exceptionally good at what they do, of that there is no doubt. I started my career at Polymicro in the late 1980: I...

Cutting capillary and making gas-tight seals is critical to good GC practice and making seals on silica press-fit connectors requires almost perfect cuts (unless you are using Pres2fit™ connectors). Cleanly cut ends are also important for CE for minimizing distortions of the electric field at the column ends. Capillary: The first thing that the separation scientist needs to understand is that not all silica capillary is the same. There are three major producers of GC and CE capillary around the world in Australia, Germany and in the USA. While very similar in materials of production, the differences in production methods...

Today I was asked a question by a prospective customer that I wish to share with the marketplace at large; that marketplace being laser surgical intervention for kidney and gall bladder stones by endoscopy. Q – I have then an additional question, why do you make 2 SMA version adapted to different brand of laser box. When I look at most of urology company offers, they mentioned that their fibers are compatible with SMA connector but indistinguishably if there are specific for Dornier/AMS or Quanta/Lumenis. What is the difference between the referenced fibers (LT/TG): power limitation? A -...
