Same Separation, Speedier Solution
Designed with GC-MS users in mind, Restek’s GC Accelerator kit provides a simple way to speed up sample analysis. By reducing oven volume, these inserts allow faster ramp rates to be attained, which reduces oven cycle time and allows for increased sample throughput and more capacity to process rush samples. When faster ramp rates are used, existing methods can be accurately scaled down to smaller, high-efficiency, narrow-bore columns using Restek’s EZGC method translator. With a scaled-down column, a properly translated method, and a GC Accelerator kit, you can obtain the same chromatographic separation—often with greater sensitivity—in a fraction of the time without making a capital investment.

As part of the global drive to reduce pollution worldwide, the International Maritime Organisation has set a global limit for sulphur in fuel oil used on board ships of 0.50% m/m (mass by mass) by January 2020 which represents a significant reduction from the current 3.50% m/m. Combustion Ion Chromatography (CIC) could play an important role in the analysis of fuel oil for sulphur content to ensure compliance with emissions targets.
automation system for leading range of benchtop NMR analysers
When fabricating gasoline from gas oil it is essential to evaluate the build up of carbon residue. Carbon residue is formed by evaporation and thermal degradation of material containing carbon.
Petroleum products contain ash-forming components which decompose during distillation using atmospheric pressure techniques so understanding the carbon residue value of carbon deposits from unrefined petroleum remnant is important when producing valuable commercial oils and lubricants.
The test method ASTM D524 uses a Ramsbottom glass coking bulb when determining the amount of carbon residue within the test sample. The glass coking bulb is made of heat-resistant borosilicate glass and should be manufactured to dimensions that meet the ASTM standards. In this case the coking bulb needs a capillary tip with an opening that measures between 1.5 to 2mm to allow for the insertion of a rod with a diameter of 1.5mm.
Crystal Science USA Corporation has a team of staff with over 30 years’ experience in manufacturing glassware to ASTM specifications using borosilicate and quartz materials. These durable glass materials have clear cost advantages and during the lifetime of the product offer better accuracy of results than other glass materials.
Atilano Martinez, CEO of Crystal Science USA Corporation, says “we pride ourselves on customer service, in addition to providing high quality products. Crystal Science offer design and engineering services enabling us to provide the petroleum market with bespoke solutions for specific applications or special projects.”
Oxford Instruments has launched MQ- Auto, a sample automation system for the MQC+ range of benchtop Nuclear Magnetic Resonance (NMR) analysers. MQ-Auto is a robotic system designed to extend the working time of the MQC+ and free up laboratory staff for more intensive tasks.
ADVANTAGE
The MQ-Auto system is based around a high- performance robot arm and a range of sample racks and conditioning stations. An optional balance can be incorporated for applications that require samples to be weighed, and a barcode reader is also available for sample identification.
The MQ-Auto is controlled by software running on either the internal computer of the MQC+ instrument, or on an external PC. The software allows samples to be run against different calibrations, and also allows operation to be paused mid-run for additional samples to be added. Optional barcodes can be attached to sample tubes to identify the sample and to store the tare weight of the tube for measurements that require weighing.
Operator safety is of course paramount with any electrical or mechanical installation, so comprehensive safety features have been built into the MQ-Auto. The robot arm itself is a so-called “collaborative robot”, designed to stop automatically if any obstruction is encountered in its path. In addition to this, the entire autosampler installation is housed in a transparent enclosure interlocked to shut down the robot arm if the door is opened. This two- level security protection ensures that the system can be operated safely with confidence.
Pure Chromatography
Kevin Nott, Product Manager, Oxford Instruments said, “The MQ-Auto uses pioneering robotics to enhance the productivity of time domain NMR analysis and like the MQC+ it is interfaced with, it does not require an expert to use it.”
