Grace Davison LC Certified autosampler vials

Grace LC Certified autosampler vials ensure that peaks come from your samples and not your vials. Through stringent traceability, manufacturing and HPLC testing, Grace LC Certified vials eliminate many of the pains that vial troubles can bring.

Vydac MS reversed-phase HPLC columns

Vydac has introduced the MS family of reversed-phase columns for large biomolecule separations. Used for separating intact proteins and the peptides resulting from protein digestion.

Grace Davison Discovery Sciences amino and diol phase flash cartridges

Grace Davison Discovery Sciences has launched flash cartridges in amino and diol phases which allow fast, easy purification of challenging polar compounds such as carbohydrates and improve selectivity for non-polar compounds such as lipids.

EnSight biodiesel analyser

The EnSight biodiesel analyser can be used to monitor reactions, determine total glycerine and profile feedstock oils, all with a single instrument.

HPLC prep column packer

The Grace Davison Discovery Sciences Multipacker Series 2002 Instruments are designed to pack preparatory columns from 25 to 101 mm ID. The instruments are easy-to-use, high performance packing stations specifically designed for Spring Column Packing.

HILIC columns

Hydrophilic interaction chromatography (HILIC) is suitable for separating and retaining very polar compounds that do not retain or have very limited retention on traditional reversed-phase packings. HILIC columns retain highly polar compounds with only small amounts of water in the mobile phase. These more volatile mobile phases increase sensitivity with LC/MS applications. Water is used as the strong solvent so increasing water content will elute peaks faster.

ELSD 2000ES evaporative light-scattering detector

Alltech's ELSD 2000ES combines universal detection capabilities with enhanced sensitivity for demanding applications.

IC/HPLC

Alltech's 650 conductivity detector and 630 column heater can be added to an LC system and data station, adding IC capabilities to the system.

Convert HPLC to IC

Alltech's suppressors and 650 Conductivity detector easily convert any HPLC into an IC system. Both suppressor models, the 640 and 641, are continuously regenerated with no need for extra reagents.

Online degassing

Alltech offers two families of degassers to eliminate the problems of unwanted air - the advanced featured Elite On-Line Degassing Family and the economical Select On-Line Degassing Family. The efficient teflon AF membrane, the continuous-run vacuum pump, and NO-OX tubing work together to consistently and rapidly remove gas from mobile phase and keep it that way as it travels to the pump inlet. Reproducible pump flow rates and stable baselines are achieved by using the degasser.

Evaporative light scattering detector

Alltech ELSD 800 is an evaporative light scattering detector that can add universal HPLC detection to any LC system to replace or complement existing detectors. The ELSD's universal response gives a closer representation of sample mass than UV detectors, making quantification more accurate when standards are not available. It can be used in parallel with MS to obtain maximum structural and concentration information for each sample. Unlike RI detectors, the ELSD offers high sensitivity, equilibrates quickly and is gradient compatible.

SPE C18 Columns

The Prevail range of water wettable C18 SPE columns does not require traditional preconditioning with an organic solvent. This eliminates organic preconditioning thereby reducing handling and disposal of hazardous organic solvents. It will also eliminate one step from typical SPE procedures with accompanying savings in time and, because it is a standard silica-based C18 sorbent, it can be substituted directly into methods or established protocols that call for C18 without the need for recalibration. It performs just as well as standard C18 sorbents with and without organic preconditioning, so it can be used for any C18 application and sample type.

Helium Detector

Alltech's helium leak detector is a portable gas leak detector that pinpoints leaks in applications such as gas capillary systems in difficult to reach and confined locations. The detector uses a highly sensitive thermal actuated cell and signal amplification to detect leaks. When a leak is detected, a signal is displayed on the unit's LED display as well as sounding an audible alarm.

Capillary Columns

Econo-Cap Capillary Columns are claimed to be identical in construction, quality and performance to other premium lines of capillary GC columns.
