Autosampler Series Features the Lowest Total Cost of Ownership in the Headspace Market
HT2000H series autosamplers by HTA represent the ideal solution for headspace injection in GC and GC-MS analysis, featuring innovative functionality, ease of use and extraordinary performance to satisfy the most demanding needs.
HT2000H series include 3 different models: HT2000H, the standard headspace autosampler that can handle 42 vials and is equipped with a 6 position oven; HT2100H, the autoinjector that represents the optimal alternative to manual headspace offering automation for processing up to 14 samples; the latest model HT2000HT, that extends support to high temperature applications, featuring sample incubation temperatures up to 300°C.
HT2000H headspace injection is made by means of a high performance, gas-tight heated syringe. This is a simple and robust system that eliminates the dead volume and absorption effects, typical of sample loops and transfer lines, which can also impede their detection at very low levels. The HTA syringe-only concept allows for sequential injections, even with samples characterised by highly dissimilar features. Even the most chemically active compounds can be analysed, without needing to change any of the sample pathways. Furthermore, it permits adjustable sample volumes without loop changes.
HTA headspace autosamplers leverage on new patented technology that enables system integrity test and vial leakage check, to provide additional robustness to the headspace analysis.
HT2000H series autosamplers, through an innovative quick-fix mounting kit, allows the installation on all GCs and GC/MSs (brand and model independent) and also the autosampler hot-swap: you can remove the autosampler and put back in place, without any complex mechanical disassembling-reassembling operation. Therefore the headspace autosampler becomes a plug-in module easy to move across different GCs as soon as lab productivity changes.
Despite its undoubted quality, HT2000H series represents also a cost effective choice.
HTA customers start saving on day 1 by purchasing the autosampler at a very competitive price, and continues to save thanks to the lowest total cost of ownership on the market. The HT2000H does not need carrier gas as gas is used only for purging between samples. In addition, it has no o-rings or seals to replace, saving hours of unnecessary downtime. Finally, it does not require magnetic or special caps, because vial transport is positive and reliable. It also allows to shut off heating when the run is completed, in order to reduce electrical consumption.

New NH2 (Amino) HPLC/UHPLC Columns are Ideal for Sugar Analyses
New ACE NH2 (Amino) columns from Advanced Chromatography Technologies are based on a proprietary bonding technology which provides high robustness and excellent column lifetimes. This high stability amino phase is ideal for the analysis of sugars and can be used in RP, NP, weak-anion exchange and HILIC modes. Available with ultra-inert, high efficiency 1.7, 3 and 5µm particles, ACE Amino is one of a wide range of carefully engineered ACE UHPLC/HPLC phases. These phases incorporate the latest developments in stationary phase technology in order to provide chromatographers with more choices for alternative selectivity but without compromising stability or robustness. Other phases include the ACE C18-AR which combines the hydrophobic characteristics of a C18 phase with the aromatic selectivity of a phenyl phase, the ACE C18-PFP which combines the hydrophobic characteristics of a C18 phase with the alternative selectivity offered by a pentafluorophenyl phase and the ACE C18-Amide and the ACE CN-ES (both phases offer alternative selectivity and are especially recommended for improved retention of polar compounds). Other products include the ACE SuperC18, a highly inert, highy pH stable C18 phase and ACE UltraCore, solid-core technology particle columns providing high efficiency separations but at reduced back pressures.
