Analytical Instrumentation Improve Your GC Accuracy and
Reproducibility With One Incredible Tool One of the secrets of good gas chromatography analysis is ensuring your GC is set up correctly. This means ensuring your detector gas flows, split flows, and column flow rates are all calculated correctly and then set accurately.
The 7000 GC Flowmeter has been designed specifically for use with GC to address these problems and to help you achieve better chromatography.
Restek’s 7000 GC Flowmeter is calibrated for the 7 most common gasses used in Gas Chromatography (Nitrogen, Air, Helium, Hydrogen, Carbon Dioxide, Oxygen, Argon and Argon/Methane). With a resolution of 0.1ml/min and an
accuracy of +-2.5% or 0.4ml/min it allows you to easily and accurately measure and set flows on your GC. Users can enter their column details and have the linear velocity in cm/sec automatically calculated and displayed. Split-flow mode allows a user to record the column flow and then measure the spit outlet flow to give a live display of both the split flow and the split ratio.

A Good Choice for Haze Determination Achieves ASTM D8148-17 Designation
Choice Analytical Inc.’s technique and instrumentation have been designated as the ASTM D8148-17 Standard Test Method for the spectroscopic determination of haze in fuels. This new test method and instruments, The Choice Analytical Clarity Choice hz and Color Choice hz, provide an efficient and effective alternative to the highly subjective visual grading method D4176 Procedure 2, which is currently being used in the majority of laboratories across the world.
“The achievement of obtaining the ASTM method is a significant step in the continued growth of the Choice Analytical Inc. full line of automated Haze and Color instruments,” said Choice Analytical president Ranzy Morgan.
The ASTM D8148-17 method involves a spectroscopic procedure, which determines the level of suspended water and/or particulate contamination, or haze, in liquid light and middle distillate fuels, including those blended with synthesized hydrocarbons or biofuels.
In addition to the conventional haze rating system, the ASTM D8148-17 method provides its user with a much more definitive Haze Clarity Index (HCI). This index breaks the clarity of the fuel into a proprietary 100-50 rating scale, with 100 as the most optically clear.
“By providing both the 1-6 scale familiar to the industry along with the 100-50 Haze Clarity Index (HCI), the Choice Analytical systems allow fuel producers and transporters to move away from the highly subjective jars and bar charts and truly move Haze measurement into the 21st century,” said Morgan.
The Choice Analytical Clarity Choice hz and Color Choice hz use a unique set of optics to achieve unparalleled precision in what was formally a decades old visual rating system.

Dutch viscometry specialist Omnitek BV (the Netherlands) provides a unique instrument with the S-flow 3000 VI : a fully automatic, double bath Houillon viscometry system, containing 4 tubes in each bath. Based on the same principles as the single bath version, it offers very quick analysis (in excess of 120 samples per hour), small sample size (only 0.5 ml) and very low solvent consumption. In addition, the S-flow 3000 VI features a high resolution touch screen, automatic Viscosity Index Calculation and optional duplo measurement capability, allowing the same sample to be measured twice in one run.
The line of S-flow viscometry systems have been the instrument of choice for many labs, with over 600 units installed worldwide. Supported by a strong network of dedicated distributors, Omnitek continues to expand the range of models to cater to a wide variety of applications.
