Milford, MA, November 16, 2016 – Waters Corporation today unveiled two new packed column products, Waters CORTECS T3 and CORTECS Shield RP18, which will further enrich CORTECS® chromatography Column product line. These new CORTECS columns not only help scientists get more information from a single analysis, but also reduce the cost of complex samples such as biomarkers, natural products, counterfeit cosmetics, synthetic cannabinoids, veterinary drugs, drinking water. And vitamins, etc.
Doug McCabe, Director of Product Management at Waters Consumables, said: "Now, scientists hope to use more efficient tools to improve the resolution, selectivity, sensitivity and separation speed of UPLC, UHPLC and HPLC. Waters CORTECS columns With its superior quality, it achieves excellent batch reproducibility and analytical stability to meet the needs and expectations of our customers."
Compared to fully porous particle columns of the same particle size, the CORTECS UPLC 1.6 μm particle column can increase separation efficiency by nearly 40% when combined with the ultra-low diffusivity ACQUITY UPLC instrument platform. Efficient CORTECS 2.7 μm particle columns are available for both ACQUITY Arc UHPLC systems and Waters Alliance HPLC systems, enabling efficient operation at lower column pressures, allowing analysts to use longer columns to increase resolution and reduce analysis time. At the same time increase throughput.
The introduction of CORTECS T3 and CORTECS Shield RP18 fillers will further enrich the CORTECS product line and form a strong product lineup with existing C18+, C18, C8, phenyl and HILIC fillers. All CORTECS columns are fully scalable between 1.6 μm and 2.7 μm. It is worth mentioning that CORTECS T3 and CORTECS Shield RP18 packing offer 48 unique column configurations for immediate global availability.
Everything comes from the filler
CORTECS columns combine a wide range of particle properties with innovative charged surface modification technology for a wide range of applications.
The CORTECS T3 column provides balanced retention of polar and non-polar molecules when operated under reversed-phase LC conditions. With a larger pore size (120? vs. 90?), lower C18 bonded phase density, and patented capping technology, CORTECS T3 Packing can perform analysis with 100% aqueous mobile phase without worrying about stationary phase dewetting.
The Shield RP18 column packing embeds the carbamate functionality into the alkyl bonded phase. It has an alternative selectivity to basic compounds and polyphenolic compounds compared to conventional C18 bonded phases. Since the embedded polar urethane group acts as a hydrogen bond acceptor, the filler has a unique selectivity, especially for basic compounds and polyphenolic compounds.
The main function of the edge banding is to seal the cross-section of the board, so as to avoid the damage of the board and the adverse factors (mainly moisture) in the process of use and prevent the formaldehyde inside the board from volatilizing, and at the same time achieve the effect of beautiful decoration.
The product has the following main features: smooth surface, no blistering, no ribbing, moderate gloss, smooth surface and back surface, uniform thickness, uniform width, reasonable hardness, high elasticity, good quality, strong wear resistance, trimmed and sealed The color of the side and the side is close to the surface color, not whitish, good gloss, and the overall color of the finished furniture is coordinated.
The role of edge banding:
First, the edge banding has the function of blocking harmful gases such as formaldehyde
Good edge banding or multi-sided edge banding can reduce the amount of formaldehyde emission per unit time (ie, slow down the emission rate). It is worth noting that edge banding will not reduce the formaldehyde content of the board, but this has the advantage of edge banding. It can reduce the formaldehyde emission per unit time of unenvironmentally-friendly sheets to a level that is acceptable to humans and does not affect health.
Second, the role of beautifying furniture
Good edge banding has the effect of beautifying office furniture, but if it is to be beautiful, the requirements for edge banding will be higher. Not only must the edge banding and the end surface of the board be firmly and smoothly combined, but also that the edge banding must be combined with other The joints of the surfaces should not have defects such as bottoming, chipping, and large gaps, and the transition should be natural, smooth and smooth.
Third, extend the service life of office furniture
The precise edge sealing design of the board can prevent water or other liquids from entering the board, avoiding the expansion, deformation and breeding of bacteria on the desktop, thereby prolonging the service life of the office furniture, and the office furniture after the edge sealing treatment is also more expensive in terms of cleaning easy.
Fourth, avoid sharp edges and corners from hurting people's bodies
The general edge banding will use the dull edge banding design to smooth the corners of the table, thereby reducing the damage to the body by the sharp corners
