Tilbage til startside for Thermo produkterThermo Fisher Scientific offers many columns and accessories for your LC/MS system, including hardware designs to optimize connectivity, speed, sensitivity, ionization technique and sample size.
Capillary LC/MS Optimization KitThe Capillary LC/MS Optimization Kit contains everything that you may need to convert an LC/MS method from narrowbore or microbore to capillary LC , including flow splitter components, tubing, sleeves and nuts and ferrules compatible with Waters®, Rheodyne® and Valco® fittings. The Capillary LC/MS Optimization Kits are designed to easily scale down your LC/MS method from microbore or narrowbore to capillary LC. Capillary chromatography is ideal for situations where increased sensitivity is required or when only very small amounts of sample are available for isolation and analysis. Kit options are available to easily optimize electrospray, microspray or nanospray interfaces for proteomics. The Capillary LC/MS Optimization Kit contains everything that you may need to convert an LC/MS method from narrowbore or microbore to capillary LC , including flow splitter components, tubing, sleeves and nuts and ferrules compatible with Waters®, Rheodyne® and Valco® fittings. Options include PicoTip™ spray emitter tips in several sizes for nanospray LC/MS methods and a steel needle option for the Finnigan® ESI source. Also included in every kit is a rugged KAPPA® capillary column packed with your choice of premium phase from Thermo Fisher Scientific including BioBasic® phases ideal for peptide and protein separations in proteomics. Capillary columns are available in 500, 320, 180, and the new 100µm I.D. The kit includes an in-depth instruction manual with detailed, easy to follow instructions to re-plumb any standard HPLC instrument to be adapted for use with capillary columns, as well as a technical discusssion on scale-down, dead volume, flow splitting and flow rate considerations. Kits can be purchased to convert Finnigan NSI (10.5cm spray emitter tips) or other manufacturers (5.0cm spray emitter tips) mass spectrometers, as well as a steel needle option for electrospray applications. They are available with your choice of capillary column (500, 320, 180 or 100µm ID and 50 to 250mm length) in a variety of premium phases including BioBasic (18, 8, SCX), HyPURITY (C18, AQUASTAR), and BetaBasic (18, 8). If you do not see the column that you require, please contact customer service.
DASH/ HTS LC/MS Columns
DASH HTS columns are packed to the same high standards as our analytical columns, and offer superioir chromatographic resolution in a design that eliminates the need for endfittings and wrenches during column change over. This makes column installation and change over faster for high through put systems. DASH HTS columns are offered in 20x2.1mm size in a variety of high performance 5µm particle size phases – including Hypercarb, BioBasic, AQUASIL C18 and BETASIL. As the columns are designed for high throughput laboratories, we offer a cost-effective solution in DASH HTS multi-packs. Packs of 3 and 10 columns can be purchased, with a quality control packing certificate for one column in every pack. We recommend DASH HTS columns are used with PEEK® tubing and endfittings. We offer a DASH endfitting and a 0.5µm porosity DASH filter, which are both knurled in black PEEK finish for ease of use. DASH HTS columns are available in any Thermo Scientific phase in single or multi packs. Please contact us for more information if you do not see the exact column that you are interested in.
KAPPA Capillary HPLC Columns
Capillary and nanobore columns are ideal for applications which require high sensitivity. However, in order to take full benefit of the improvement in performance when capillary and nanobore columns are used, band dispersion, which causes sample dilution and loss of sensitivity, needs to be minimized. Using short lengths of capillary connecting tubing and optimal injection volumes can minimize extra-column band dispersion in LC/MS analysis. Designed to give exceptional results under demanding LC/MS conditions, KAPPA capillary and nanobore columns are manufactured from inert tubing with internal diameters of 500, 320, 180, 100 and 75µm. Lengths are available in 50, 100, 150 and 250mm, as well as 30mm guard columns (500, 320 and 180µm ID) for extending analytical column lifetime. All columns terminate in unions that are compatible with 10-32 male nuts and 1/16” OD capillary tubing. The stainless steel sleeve makes KAPPA columns robust and easy to handle. KAPPA capillary and nanobore columns are available in a wide variety of Thermo Scientific phases, including BioBasic, HyPURITY, BetaBasic and Hypercarb packings. If you do not see the phase or dimension you are interested in, please inquire. KAPPA capillaries are also available in a flexible fused silica design with 1/32” PEEK fittings at both ends of the column to connect to the 10-port switching valves. KAPPA capillary and nanobore columns are ideal for high sensitivity LC/MS applications when sample size is limited. KAPPA column sizes are ideal to use with microelectrospray and nanospray. Analytes at the picomole and femtomole levels can easily be detected, identified and quantified. KAPPA capillary guards are designed to extend the lifetime of KAPPA columns. They protect the analytical column from particulates and from contamination from the sample or mobile phases. KAPPA guards are available in 30mm length and 500, 320 and 180µm IDs. Please contact your local Thermo Fisher Scientific office for more information. Nanoflow Column
Thermo Scientific columns are available in nanobore formats for nanospray LC/MS applications. At flow rates of nL/min versus mL/min, they offer higher sensitivity with greater signal-to-noise ratio than traditional capillary columns used with electrospray. Analytes can be detected, identified and quantified at femtomole levels and below. IntegraFrit™ columns have an integral highporosity frit, behind which is the packed chromatography bed. The frit end of the fused-silica column is polished flat to ensure a clean connection to the emitter of choice. PicoFrit® columns eliminate post-column performance losses by spraying directly from the column tapered end, boosting MS performance compared to that provided by a column attached to a tip.
