UHPLC Autosampler Provides High-Speed Analysis

Shimadzu Scientific Instruments has launched the SIL-30ACMP autosampler for the Nexera Ultra High Performance Liquid Chromatograph (UHPLC). The SIL-30ACMP combines with the optional CTO-30AS column oven to create a front end suitable for all LC/MS systems. Shimadzu claims that, when paired with its LCMS-8030 or LCMS-2020, the autosampler allows users to configure a complete high-speed LCMS system, capable of analysing multiple samples accurately, quickly and with low carryover.

The SIL-30ACMP holds up to six plates for increased capacity. Using 384 well plates, the SIL-30ACMP can perform continuous analysis on 2,304 samples, which Shimadzu claims is the highest number of samples that can be analysed in a closed-type, safe-design autosampler. It can also continuously analyse 324 samples using 1.5ml vials. For versatility, three different plate types can be set in the sample racks simultaneously. The system also houses a standard/control sample rack holding 1.5ml vials, which is useful while testing multiple unknown samples with microtiter plates.

The optional CTO-30AS mounts directly on the side for close proximity to the autosampler and can be positioned from the vertical to the horizontal to minimise tubing lengths. This reduces extra column band broadening effects, which Shimadzu claims is especially important for UHPLC applications. With its open-access design, the SIL-30ACMP permits users to access the sample racks at any time, except during the injection process. Building on the proven Shimadzu design, the autosampler provides low carryover of 0.0015 per cent or less, minimising sample contamination. It provides reproducibility of one per cent or less in 0.5ul injections and of 0.2 per cent or less in injections of 5ul or more. According to Shimadzu, the autosampler also offers the world's fastest cycle time at 14 seconds.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa...

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin...

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
