etrohm NIRSystems has many advantages over other methods of analysis, including speed (seconds), the fact that it is nondestructive, it requires no chemicals or solvents, and it is capable of performing analysis on a number of components simultaneously. NIRSystems has successfully implemented NIRS for petrochemical analysis in the laboratory, as well as directly into processes in refineries. NIRS was first used in the analysis of Research Octane Number (RON) in gasoline in the late 1980s. The main use of the analysis was for octane-blending and it helped minimise the ‘octane giveaway’ by controlling this process in
real time online. In addition, other parameters such as aromatics, olefins, oxygenates, and Reid Vapour Pressure (RVP) are simultaneously measured. Samples are scanned as-is, either in laboratory instruments (in cuvettes or disposable vials) or in process streams (using fibre-optic probes). Diesel blending can similarly be monitored by NIR and, in addition, the NIR analysers can also be used in a number of other parts of the petrochemical refinery. NIR has been used successfully to monitor the input and output streams of Crude Oil Distillation units, Naphtha Crackers, Reformers, and other downstream processes such as para-xylene.

nton Paar has launched Diana 700, the ideal solution for automatically performing high-precision distillation range analysis at atmospheric pressure. Typical samples to be analysed include petrochemical products, aromatic hydrocarbons, and other volatile organic liquids. The combination of premium technology and distinguished features leads to unrivalled ease of use, high efficiency and safe operation. Support and automation for reliable results To simplify the preparation of a measurement, Diana 700 supports you with several built-in features to provide maximum support. The intelligent condition-monitoring system controls all steps that are necessary to perform a distillation and only allows a start if every step was completed successfully. Users do not lose time on test repeats due to an incorrect setup or non-compliance with the standard. The instrument has a high degree of automation as the heater and a protection shield move up fully automatically after the flask has been installed, using the unique and mobile multi-plug. Untrained users benefit from illustrations that explain the procedure that is necessary to start a distillation step by step. For experienced users, the advanced mode enables a quick start. Convenience combined with efficiency For a smooth operator experience and to increase the usability of the instrument, the

The SRI Model 310 medicinal herb GC (Gas Chromatograh) analytical system (available only from Chromspec in South Africa) tests cannabis (marijuana) for basic cannabinoids (THC, CBD, CBN, etc.), basic terpenes (pinene, myrcene, limonene, etc.), as well as basic residual solvents (methanol, ethanol, etc.). It is a fast, simple, and precise way to test your product, while providing a laboratory grade analysis. And … no chemistry qualification needed! No external gas cylinders are required to operate the model 310 medical marijuana GC system, as it is equipped with a built-in hydrogen generator and air compressor.

Is your lab equipment receiving the cleanest possible gas?
Medical Cannabis Analysis Why use expensive and slow contracting labs for the analysis of your product, when you can do the analysis yourself?
multi-plug combines the vapour temperature sensor and the flask-mounting device. With just one hand, it is possible to install the 125ml or 200ml flask within seconds in the correct position. The receiving chamber of Diana 700 ensures very easy operation. Thanks to the tight jacketing of the receiving cylinder, the cooling chamber guarantees an excellent stability of the sample and cylinder temperature. Considering valuable customer feedback and using state-of-the-art technology, Anton Paar designed Diana 700 as a modern and easy-to-use instrument. Several built-in features provide support, efficiency and safety. For more information follow the link: https://www.anton-paar.com/us-en/ products/details/atmospheric-distillationanalyzer-diana-700/

id you know that many labs these days are using their equipment with either sub-standard gas filters or no gas filters at all? In this time of economic downturn, many companies are choosing to economise on filters in the hope that what they are purchasing is “good enough” or trusting in their gas suppliers’ certificates that everything is as it should be. When it comes to laboratories, “good enough” just isn’t good enough. Chromspec CC is proud to announce a renewed partnership with SGT (Singapore Glass Technologies), a world leader in gas filtration technology. SGT is ISO 9001 approved, so you can rest assured that you are getting the highest possible gas to your laboratory equipment. They also supply a unique electronic indicator to
let you know when your filter is due for replacement. Some of the risks of using gas with impurities and sub-standard filters include (but aren’t limited to): • Ghost peaks • Missing peaks • Fluctuating baseline • Invalid results • Shorter column life • Premature equipment failure • Potential loss of laboratory certification
