12 New GC Gas Calculator Introduced
Peak Scientifi c has created a unique online calculation tool to help laboratories which use Gas Chromatography (GC) to quickly fi nd the ideal gas solution for their specifi c GC instrument.
• • • •
The aptly named ‘GC Gas Calculator’ consists of 6 simple questions regarding a user’s GC instrument, such as the number and type of GCs, detectors, columns and injectors. These questions can be quickly and easily answered to determine the best gas supply solution for the GC instrument indicated.
Peak’s user-friendly calculator is free to use and generates a simple report which Peak Scientifi c will provide to anyone who uses the calculator.

No Frills HPLC Autosampler Delivers What You Truly Need
IF your HPLC routine calling for automation, look no further than the HT1500L: an autosampler specifi cally designed for HPLC, fully equipped with all the powerful features any HPLC technician would naturally choose.
HT15000L is the new HPLC autosampler from HTA that offers the best balance of quality and affordability and that is perfectly compatible with any HPLC system.
Unlike LC-MS, nanoLC and UHPLC systems, the HPLC requires few, essential features: excellent analytical performance, good sample capacity, and of course, uncompromised reliability, robustness and durability. HTA has showered the HT1500L with all these essential features, while eliminating anything unnecessary to keep costs as a minimum.
No frills but even no compromise. Despite the competitive price, HT1500L has a strong commitment to quality: the materials have been picked up to provide longevity; the up-to-date technologies offer reliability that deserve a modern instrument while the design attests our care in details.
HT1500L holds multiple racks, each of them removable, to allow continuous sample feeding and more convenient operations. The on-board solvent reservoir allows the needle and the whole fl owpath cleaning before processing the next sample.
HT1500L comes with HTA Autosampler Manager, HTA complementary software for autosampler programming. After setting the method once, the operator just needs to load samples and presses START: all the samples in the racks will be automatically processed. Seamless integration can also be experienced with the currently used Chromatography Data System.
HT1500L can actually become your workhorse, extremely reliable and straight to the point.

Targeted Analysis and Accurate Profi ling of Volatiles and Semi-volatiles in High Complexity Samples
GC×GC-HRMS is one of the most powerful tools available to analytical chemists for the targeted analysis and accurate profi ling of volatiles and semi-volatiles in samples of high complexity. This technique combines the excellent resolving power granted by two-dimensional separations with accurate mass measurements that provide a substantial advantage for identity confi rmation. It is therefore not surprising that GC×GC- HRMS is increasingly more accepted in labs dealing with challenging analytical requests in very complex matrices such as, for instance, environmental and food analysis.
JSB recently investigated the use of GC×GC with Zoex thermal modulation coupled to an Agilent QTOF detector for quantifi cation of organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs). These compounds are synthetic chlorinated compounds banned or restricted due to their toxicity to humans and impact on the environment but, being persistent pollutants, are still present as residues in soil, water, food etc. Their identifi cation and quantifi cation is of great importance for environmental and food safety since they represent a risk even at very low level. The QTOF grants wide operational fl exibility allowing EI and CI acquisition, as well as MS/MS capability. In this example JSB selected the NCI to obtain higher sensitivity for the halogenated compounds. The results obtained for linearity and repeatability show that GC×GC with thermal modulation and QTOF are robust and provide performance suitable for reliable identifi cation and quantifi cation at low concentrations.
