Milford, MA, August 23, 2016 – Waters Corporation (NYSE: WAT) recently launched a series of new chromatographic connectors and new micro-upgrade analysis at the 21st International Mass Spectrometry Conference. Column. For scientists using nanoscale upgrades to micro-upgrading liquid chromatography (LC), the introduction of this new product will greatly enhance scientists' peptide bioanalysis, pharmacokinetics and endogenous peptide biomarker validation. Work efficiency.
Waters ionKey/MS micro-upgraded chromatography products now include two iKey analytical columns with internal diameters of 150 μm and 300 μm
High-throughput microfluidic LC-MS – for just three minutes, for superior analytical sensitivity
As the newest member of Waters' ionKey/MSTM micro-upgraded chromatography product, the Waters® 300 μm ID column iKeyTM HT is a “ceramic†engraved with a 300 μm id channel (filled with 1.7 or 1.8 μm UPLC® packing). An ideal alternative to traditional capillary columns. Compared to the previous 150 μm id iKey, the new iKey HT has a larger inner diameter of the microchannel for higher flow rate separation analysis, reducing run time to three minutes or less, and LC with traditional 2.1 mm id columns. The separation performance is comparable.
A recent Waters article describes a study using plasma samples from six small molecule analytes precipitated on the same BEH C18 iKey HT column (300 μm x 50 mm, 1.7 μm). Injection analysis of 1,000 needles. The results showed that the area variation coefficient (% CV) of the continuous injection needle was less than 5%, the sensitivity was at least 2 times higher than UPLC/UHPLC, and the running time of each sample was no more than three minutes [1].
The Waters 300 μm ID X 50mm (L) iKey HT column has the following fillers: BEH 130Å PsT C18, 1.7 μm; CSH 130Å PsT C18, 1.7 μm and HSS T3 100Å, 1.8 μm.
During the 2016 International Mass Spectrometry Conference (IMSC), Waters will host a breakfast seminar at the 715 on the Toronto Convention Center from 7 am to 8 pm on August 24 (Wednesday) to meet participants from around the world. Introducing the Waters iKey HT series.
Waters' earlier ionKey/MS system (using 150 μm iKey) was awarded the highest innovation award from the 2014 Analytical Scientist magazine and the 2015 R&D 100 Award.
New micro-upgrade chromatography dedicated ZenFit tubing kit and hand-wound connector
Sample preparation methods have a critical impact on the results of the analysis, especially for the separation of nanoliter flow rates and micro-upgrade flow rates. Even if it has been considered very thoughtfully, the connecting pipeline in the liquid phase system will inevitably become blocked, and the only countermeasure is to replace the blocked pipeline. Inexperienced analysts can easily overtighten the joint, causing the pipe to break or chip. Waters' new ZenFitTM tubing kit features a hand-twisted fitting that incorporates ZenFit connection technology, allowing easy replacement of the connecting tubing with a single twist.
Concerned about surprises
Flexible Diamond Sanding Belts
Diamond Electroplating Abrasive Belts are nickel-plated as a binder and are made from diamond powder. Diamond electroplated abrasive belts consist of a backing material, a metal base, and an array of diamond coatings. The backing material and the flexible metal substrate are bonded to form a ring-shaped super-hard coated abrasive. As a result of special stainless steel, double-layer backing and selected high-quality diamonds, our flexible diamond belt a very fast chip, the chip minimum, very long lifetime to achieve good tempering results, it can be done all the games. Our flexible diamond belt is widely used in wet and polishing applications in the aerospace, ceramics, glass, paper and stone industries. The advantages are consistency, increased productivity, reduced downtime and wear costs. The average life expectancy of our diamond abrasives is 1,000 times longer than that of conventional abrasives compared to conventional abrasives. Most sizes are available for many applications on hand-held or robotic machines and all sizes are available or can be made as a fit-to-hand, cross belt and robotic machine.
1.1 Compared with ordinary abrasive belt
Diamond electroplated abrasive sanding belt has the characteristics of hardness of superhard material and the softness of the coated abrasive. The working layers is arranged, making the gap between the small units of the working layer larger, there will be a bigger chip removing space, it is good for cooling, improving the processing quality, flexible of sanding belt and chip removal capacity. It is low noise and little dust when using.
1.2 Compared with diamond grinding wheels
Diamond Grinding Wheel is a rigid abrasive tool. In the grinding process, there are not good self-sharpening and easy to chip . Especially when automotive wind safety glass and other material need to be processed as curved surface of hard and brittle materials, if use diamond electroplated abrasive sanding belt can improve the grinding feed rate and working efficiency. And effectively solve the problem of glass chipping and maintain the original shape of the surface very good.
1.3 Compared with diamond resin belt
Diamond resin belt has resin bonded, also has double advantages of softness of a traditional coated abrasive and high hardness of the diamond. But when grinding, the heat will be accumulated in the diamond, it the heat will not be derived immediately, the temperature will be increased immediately, resulting the bond agent melting, the diamond will fall, and the service life is short. So diamond resin belt must grind by adding water to cooling, and the cost-effective of that is worse than diamond electroplated abrasive sanding belt.
Application of Diamond Electroplated Abrasive Sanding Belt
Diamond electroplated abrasive sanding belt can be widely used in stone, glass, ceramics, monocrystalline silicon, polycrystalline silicon, synthetic materials, hard alloy, aluminum alloy and other hard and brittle material complex surface grinding processing.
