OLIGO™ R3 Reversed - Phase Resin Applied Biosystems™

Thermo Scientific™ Oligo™ R3 bulk resin is a rigid polymeric bead designed for reversed-phase chromatography of polynucleotides and other biomolecules. The combination of 30-μm particle size, resistance to high pH, and high-phase ratio, makes Oligo R3 resin particularly suited to preparative purification of synthetic oligonucleotides and peptides. The packing consists of cross-linked poly-divinylbenzene particles. Oligo R3 bulk resin differs somewhat in selectivity from conventional silica-based, reversed-phase resins and is similar to high-carbon-loading through C18 supports. In addition, the complete lack of residual silanol activity may modify the selectivity of ionic species.

Features of Oligo R3 resin and pre-packed columns include:
• High performance chromatography resin for analytical to process scale separations
• High resolution preparative purification at high flow rates
• Chemical stability—allows aggressive cleaning and sanitization
• Poly-divinylbenzene particles—yield a robust, easily packable matrix
• Combines low back pressure, high pH stability, and high capacity

SLIPFREE™ HPLC Column Single Connectors Thermo Scientific™

Ensure excellent column connections and optimal HPLC performance with Thermo Scientific™ SLIPFREE™ HPLC Column Single Connectors. Compatible with all column end-fittings, these universal, self-adjusting connectors provide leak- and void-free column connections. Fingertight connections up to 10000psi ensure ease of use. They are ideal for supercritical fluid columns (SFC). SLIPFREE connectors are available in a variety of configurations and designs for a broad range of applications.

Finger Tite Connectors Thermo Scientific™

Ensure reliable, leak-free connections for optimal GC performance using Thermo Scientific™ Finger Tite Connectors. The perfect metal-to-metal seal eliminates contamination and produces lower air/water background noise compared to conventional graphite/polymer ferrules. They are easy to handle even with a hot injector/detector and do not require the use of tools. Unlike other ferrules, they do not require retightening after installation.

POROS™ High Performance Chromatography™ Media and Pre-Packed Columns

A high performance chromatography resins for analytical to process scale separations.
• Higher productivity: High throughput and high dynamic capacity associated with High Performance Chromatography™
• Chemical stability: Allows aggressive cleaning and sanitization
• Enhanced biomolecule access: Provided via large pores, ranging between 500-10000 Å
• Polystyrenedivinylbenzene particles: Yield a robust, easily packable matrix
• Develop better separations methods in a shorter time frame: The speed of High Performance Chromatography technology reduces weeks of experimentation to only a few hours of work, so you have plenty of time to explore all the variables of your separation

Reduce time-consuming sample prep

You can replace many sample preparation steps with high speed High Performance Chromatography technology. For instance, dialysis of large volumes of material can be replaced by high flow rate processing of the dilute sample. Elution in a small volume of new buffer accomplishes both buffer exchange and concentration.

Create novel assays for more efficient analysis

High Performance Chromatography technology is not limited to standard modes of separation. Both enzymes and affinity ligands can be immobilized on POROS media. By combining rapid on-column protein digestions with rapid on-column immunoassays and chromatographic separations, you can create entirely new assays with unlimited potential.

High Capacity, High Resolution, High Speed

In contrast to conventional chromatography media, POROS™ High Performance Chromatography™ resins particles, are engineered to have two discreet classes of pores. Large "throughpores" allow convection flow to occur through the particles themselves, quickly carrying sample molecules to short "diffusive" pores inside. By reducing the distance over which diffusion needs to occur, the time required for sample molecules to interact with interior binding sites is also reduced. Diffusion is no longer limiting and flow rates can be dramatically increased - without compromising resolution or capacity. Separations can be achieved at 1,000 to 5,000 cm⁄hr compared to 50 to 360 cm⁄hr for conventional media.

Gas Chromatography Tubing Thermo Scientific™

Find copper and stainless steel Thermo Scientific™ Gas Chromatography Tubing in a variety of sizes for plumbing your gas chromatography (GC) system.

MSTFA and MSTFA + 1% TMCS Silylation Reagent Thermo Scientific™

Use Thermo Scientific™ MSTFA and MSTFA + 1% TMCS Silylation Reagent for GC analyses of early eluting compounds that would otherwise be obscured in the chromatogram. MSTFA, the most volatile TMS-amide available, and its byproduct N-methyltrifluoroacetamide typically elute with the solvent front, allowing TMS derivatives of small molecules to be analyzed. Addition of Thermo Scientific™ TMCS aids derivatization of amides, secondary amines, and hindered hydroxyls not derivatized by MSTFA alone.
