A Restek^® LC guard cartridge in an EXP^® direct connect holder is the ultimate in column protection.

To help protect your investment and further extend the life of our already-rugged LC columns, Restek offers the patent-pending guard column hardware developed by Optimize Technologies.

Raptor™ EXP^® Guard Column Cartridges Features:

Free-Turn^® architecture lets you change cartridges by hand without breaking inlet/outlet fluid connections—no tools needed.
Patented titanium hybrid ferrules can be installed repeatedly without compromising high-pressure seal.
Auto-adjusting design provides ZDV (zero dead volume) connection to any 10-32 female port.
Guard column cartridges require EXP^® direct connect holder.
Pair with EXP^® hand-tight fitting for tool-free installation.

Application NoteSeparations

Two decades of pioneering innovation with Restek’s biphenyl LC column

Achieving reliable separations in complex analyses has long challenged chromatographers, especially when working with early-eluting or closely related compounds. Traditional phases often fall short, requiring intricate mobile phases that complicate MS detection.

Learn how enhanced selectivity and robust performance can simplify method development, accelerate separations, and support confident results, even in the most demanding LC-MS workflows.

Stabilwax® (Fused Silica)
Restek Corp.
General purpose columns for FAMEs, flavor compounds, essential oils, solvents, xylene isomers, and US EPA Method 603 (acrolein/acrylonitrile). Resistant to oxidative damage. Temperature range: 40°C to 260°C. Equivalent to USP G14, G15, G16, G20, and G39 phases. The polar-deactivated surface tightly binds the Carbowax® polymer and increases thermal stability, relative to competitive columns.

Q-sep™ QuEChERS Tubes
Restek Corp.
Q-sep™ QuEChERS Tubes for Pesticide Residue Analysis • Fast, simple sample extraction and cleanup using dSPE. • Fourfold increases in sample throughput. • Fourfold decreases in material cost. • Convenient, ready to use centrifuge tubes with ultra pure, preweighed adsorbent mixes. Quick, Easy, Cheap, Effective, Rugged, and Safe, the QuEChERS ("catchers") method, developed by the USDA Eastern Regional Research Center, has become very popular for extraction and clean-up of pesticide residue samples. Our products are available in three centrifuge tube sizes to meet the needs of both extraction and cleanup of a wide variety of sample matrices following various methods. The researchers developed a simple two-step procedure. First, the homogenized samples are extracted and partitioned, using an organic solvent and salt solution. Then, the supernatant is further extracted and cleaned, using a dispersive SPE technique. Multiple adsorbents are placed in a centrifuge tube, along with the 1mL of organic solvent and the extracted residues partitioned from step 1. The contents are thoroughly mixed, then centrifuged, producing a clean extract ready for a variety of GC or HPLC analytical techniques. Validation and proficiency data for the QuEChERS method are available for a wide variety of pesticides in several common food matrices on their website.

Flip Seal Dual Vespel® Ring Inlet Seals
Restek Corp.
Reversible Flip Seal—Same Cost, Twice the Lifetime 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. •Same easy sealing as Dual Vespel® Ring Inlet Seals—no extra washer needed. •Lower leak rate than OEM metal seals. •Maximum transfer of analytes to column, due to highly inert gold or Siltek® surface.

GCxGC Columns
Restek Corp.
• Wide range of stationary phases offers orthogonal separations. • High thermal stability maximizes system ruggedness and sensitivity. • Unrivaled column inertness for accurate analysis of active compounds. • 0.15, 0.18, and 0.25 mm ID formats accommodate varying sample capacities, speeds, and detectors. • Secondary columns come in convenient 2 m lengths for economical method development. GCxGC is a powerful multidimensional GC technique that combines two independent separations to accurately analyze highly complex samples. GCxGC involves two columns with differing (orthogonal) stationary phases that are press-fitted together in series and separated by a modulator. The first (primary) column performs a separation, and its effluent is continually focused and “injected” by the modulator onto the second (secondary) column, where another separation occurs. By choosing a secondary column that is orthogonal to the primary column, it is possible to identify analytes that cannot be separated by the primary column. And by keeping the secondary column short, it is possible to maintain the separation produced by the primary column. Results generated through a series of high-speed chromatograms are plotted as a retention plane, or contour plot (column 1 time x column 2 time). Restek has been performing comprehensive two-dimensional gas chromatography since its commercial inception. Our innovations lab boasts multiple instruments dedicated to GCxGC applications, and we are continually exploring new application areas—including environmental, food safety, petroleum, forensics, fragrance, natural products, and dietary supplements. Restek GCxGC secondary columns can be matched with any Restek Rtx® or Rxi® primary column to create the perfect orthogonal separation for your application.
