InnovaQuartz pioneered the use of carbon dioxide lasers for manipulating and machining fused quartz and fused silica glasses under computer control and microscopic imaging way back in 1991 when our founder, Stephen Griffin, gambled that his ideas would actually work and built the first laser system in his 80 square foot laundry room. Our first sale was 6 months after the first dollar was spent and we sold more than $1,000,000 in machined fused quartz and modified optical fibers in the first twelve months of operation. We have stayed well ahead of all competitors who tried to copy our...
Repairing a Column with a Press2Fit™ Union

Purpose: Provide step-by-step instructions for best practices in capillary column repair Theory: GC capillary columns sometimes break on the column cage. While most of the causes of such failures are relatively benign, some may portent coming disaster (see #6 in “How to Properly Cut Capillary Columns”) and improper repair of a capillary column break can convert a benign failure into a catastrophic failure. Benign sources of failure are inadvertent, local damage in handling, polyimide erosion or abrasion due to contact with the wire cage and the occasional, random flaw manifesting itself. Such breaks are, by definition, “improper column...

The 3 Leading Causes of Column Leaks Among some chromatographers, capillary connections using press fit connectors have a reputation for leaking. Where there was a time when this was true, that time has past. InnovaQuartz collected and studied leaks from the field for a period of three years; 28 of the leaks were in our own products (of over 1,000,000 sold in that same period) and most of those were Y-splitters. We found that 98+% of leaks in press fit connections arise from three classes of problems, all of which may be addressed by a correctly designed connector: 1) Less...
