True Blue: Sky™ Inlet Liners from Restek
With their distinctive blue color and state-of-the-art deactivation, Sky™ liners make choosing the best inlet liner simple. The innovative deactivation results in exceptional inertness for a wide range of active compounds, giving you better sensitivity, accuracy, and reproducibility. Highly inert Sky™ liners allow you to quantify at trace levels with confidence, even when using wool. In addition to improved data quality, you’ll benefit from fewer liner changes and less downtime for maintenance. Choose blue—the best choice for dependable results.

Rxi®-17Sil MS Columns
The unique Rxi®-17Sil MS phase is specifically optimized for polycyclic aromatic hydrocarbons (PAHs), making it the best choice for accurate, trace level PAH detection. Rxi®-17Sil MS columns differ in phase chemistry from conventional “17” type (50% diphenyl) columns and the resulting selectivity provides better resolution of critical PAHs. Not all PAHs can be separated on typical 17 type columns—only Rxi®-17Sil MS columns let you quantify isobaric PAHs that cannot be determined by mass spectrometry.

New High Temp Rxi® GC Columns
Restek is pleased to introduce 2 new high temperature fused silica columns that are processed specifically for high temp GC applications. The Rxi®-1HT (100% dimethyl polysiloxane) and Rxi®-5HT (5% diphenyl/95% dimethyl polysiloxane) are stable up to 400 °C, ensuring better accuracy for trace level analyses at high temperatures. Like the entire Rxi® line, these rugged new columns combine exceptional inertness with a long column lifetime, giving you accurate, reliable results every time.

Flip Seal™ Dual Vespel® Ring Inlet Seals
New reversible Flip Seal™ inlet seals from Restek last twice as long as other inlet seals. Simply use—flip—then use again. The reversible design doubles the number of analyses you get per seal. These inlet seals use the same easy sealing mechanism as Dual Vespel® Ring Inlet Seals, meaning no extra washer is needed. Flip Seal™ inlet seals have a lower leak rate than OEM metal seals, and the highly inert gold plated or Siltek® treated surface helps maximize analyte transfer to the column.

Q-sep™ QuEChERS Extraction Salt Packets
Restek now offers Q-sep™ extraction salts for QuEChERS methods in convenient foil packets. These packets are easy to use and eliminate the need for a second tube when transferring extraction salts. Specific blends are available for both AOAC (2007.01) and European (EN 15662) QuEChERS methods. Simplify and speed up sample extraction for pesticide residues using these new packets and other QuEChERS products from Restek.

UltraShield/UltraLine UHPLC Filters
Protect your UHPLC system with new ultra-high pressure filters from Restek. These cost-effective 0.5 µm precolumn filters are available in standard (UltraShield) and in-line (UltraLine) configurations. Stainless steel bodies install quickly with standard parts and are leak tight up to 15,000 psi. Prevent expensive repairs with new UltraShield and UltraLine UHPLC filters.

ProFLOW 6000 Electronic Flowmeter
The ProFLOW 6000 flowmeter measures bidirectional, volumetric flow for most gases including real-time measurements for various types of continually changing gas flow paths. This portable unit is designed for easy hand-held use, and the stand adds bench-top convenience. The ProFLOW 6000 flowmeter accurately measures gases across a range of 0.5-500 mL/min. and is backed by a one-year Restek warranty.

Gas ChromatographyGas chromatography (GC) is an analytical technique used to separate and quantitate mixtures of small and volatile compounds. Gas chromatographs or GC systems include components such as GC columns, detectors, pumps and autosamplers. Choose from packed or capillary GC columns, flame ionization (FID), photoionization (PID) electron capture detectors and selective or non-selective detectors. Find the best gas chromatographs in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems. Find the best UHPLC and HPLC equipment in our peer reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.LC-MSLC-MS (liquid chromatography-mass spectrometry) systems and equipment are used for separation and quantitative analysis of complex mixtures, combining liquid chromatography and mass spectrometry. Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis. Find the best LC-MS equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Combinatorial ChemistryCombinatorial chemistry, also known as combichem, is a technique used in drug discovery to create libraries of structurally related compounds. A library is generated by synthesis with a chemical reactor system or by computer-based modeling of compound combinations. When undertaking combinatorial chemistry consider reagents, buffers, resins and standards.Lab-on-a-ChipLab-on-a-chip (LOC) technology uses microfluidic chips, such as microarrays, to perform biochemical assays on a small scale. Benefits of lab-on-a-chip include the small volume of sample required as well as the speed of analysis. In selecting lab-on-a-chip devices consider the assay, cost, reliability, sensitivity and signal to noise ratio.High-Throughput ScreeningHigh-throughput screening (HTS) is an automated drug discovery technique for identification of active compounds against a compound library.

Often the system is integrated with a mass spectrometer in nano LC-MS or nano LC-MS/MS. When using nanoLC equipment consider column choice, software and accurate and precise flow rate control.Assay AssemblyAssay Assembly is technique used in drug discovery to develop assays to test the cytotoxicity, genotoxicity, or other activities of a compound on a cell. Assay assembly requires chip assembly, a delivery system and a detection and analysis method. Beneficial features of assay kits or automated systems include high-throughput, high speed and sensitivity and low signal to noise ratio.Compound LibrariesCompound libraries, or chemical libraries, are used in drug discovery for the identification of potential therapeutics compounds. Used in conjunction with high-throughput screening, the libraries of stored compounds are often generated for specific purposes as a drug target or disease model. Cheminformatics are commonly used when designing a compound library and software can be used to analyze the screening process.  Medicinal ChemistryMedicinal chemistry is a broad discipline encompassing the design, identification, synthesis and development of chemicals in drug discovery. It includes a number of techniques covering structural biology, synthetic chemistry and molecular biology. Technologies used in medicinal chemistry include ADME, lab-on-a-chip, high content screening and assay assembly.Microarray AnalysisMicroarrays, also known as biochips, are used for the detection and analysis of multiple genes, proteins, antibodies, or biomarkers on a single microchip. This can reveal information on protein or gene expression, single nucleotide polymorphism (SNP), copy number variation (CNV), epigenetics and patient health in clinical diagnostic tests.
