CDS Analytical is a leading global provider of innovative GC thermal sample preparation instrumentation for GC/MS in the analytical lab. Home >> Products >> Purge & Trap Purge & Trap Gas chromatography is one of the fundamental analytical tools that compose the modern analytical lab, along with Mass Spectroscoy, Spectroscopy and Microscopy. However, like everything else, it does have several limitations, including lack of sensitivity, inability to tolerate water injections, and the sample must be in the vapor state. These limitations all come into play when studying aqueous samples in drinking and waste water and beverages. Purge and Trap, invented in the 60s in response to the Clean Water Act, is the most effective method to answer these challenges for extracting and concentrating volatile organic compounds (VOC) from liquids and solids. The Purge and Trap process involves purging the sample with an inert gas in a sealed environment (sparge vessle) at the appropriate temperature. The gas going through the sample will establish thermal equilibrium with VOCs in the sample, therefore transferring the VOCs from an aqueous state to a vapor. After eliminating the moisture through the wet trap, the gas is then swept to an analytical trap that absorbs and retains the VOCs , where they are transferred to the Gas Chromatograph for further analysis. CDS analytical instruments are designed around a few core concepts including EPA regulation compliance to EPA 8260, 524, 624 methods, reliability, expandability, dependability and competitive pricing. It has been acknowledged as the industry workhorse for decades. To further unleash the full power of your GC systems, we designed a full suite of products including standalone autosamplers (8500 series) and an industry first Purge and Trap tool for the popular CTC PAL systems.

Multi-channel and multi-functional parallel concentration instrument Home >> Products >> Nitrogen Concentrator Nitrogen Concentrators Family Brief Nitrogen concentrators are an alternative to rotary evaporation mainly in case of small volumes (under 50 mL) and a large quantity of samples. Nitrogen concentrators accelerate the evaporation by decreasing the partial vapor pressure of the solvent just above the surface of the liquid. Blowdown evaporators use a jet of dry nitrogen to continually force off the layer of air that is saturated with vapor. By immediately removing molecules that enter the vapor state, the molecules do not have a chance to return to the liquid, which increases the evaporation rate. As said blowdown technique is very useful for small sample volumes because with larger samples nitrogen blowdown will take longer and semi-volatile compounds may be lost. Since the samples are immersed in a water bath, with programmable temperatures up to 100°C, the evaporation is further accelerated. LabTech offers 2 fully automated nitrogen concentrator hosting different tube sizes to satisfy multiple applications. · The MV5 has 6 drying channels of 9 needles each for 54 samples of 10 mL · The M10 has 10 drying channels with individual needle for 10 samples from 50ml to 200 mL All LabTech products comply with the ISO procedures, to ensure they fully satisfy the quality standards and the needs of our customers. LabTech has indeed the UNI EN ISO 9001:2015 certification, obtained by TÜV SÜD - a global, multi-accredited organization accepted by the majority of the world - proving that we thoroughly follow the international standards for quality management.

CDS Analytical is a leading global provider of innovative GC Pyrolyzer, Thermal Desorber, Purge and Trap Concentrator for GC/MS in the analytical lab. 关于公司 产品线 产品市场及应用 技术支持 立即订阅 Home >> Products >> Thermal Desorption 热解吸 热解吸包括两个主要功能：样品采集/浓缩，和转移到检测器。 使用吸附剂和大样品体积来采集气相化合物（如空气中的挥发性有机化合物，或来自固体物的残留组分），即使样品含量非常低，也能准确分析。 有机物浓缩在吸附剂介质上，而样品基质，空气或水不会被采集。与真空吸尘器一样，当扫过一个表面时，真空吸尘器会将空气中的灰尘过滤掉，Dynatherm热解吸仪则可以将感兴趣的化合物捕获在玻璃管中装填的吸附材料上。然后将收集的化合物引入另一种分析仪器，通常是气相色谱仪，在那里分离，测量和鉴定。 热解吸使用热能（而不是溶剂萃取）从吸附剂中释放有机化合物，并将整个收集的样品转移到气相色谱仪进行分析。这消除了萃取时间（通常为12-24小时），色谱图中的溶剂峰值（可掩盖目标化合物）和废溶剂处理，而这些支出在许多实验室中正在不断增加。 该过程灵活方便。例如，配备电池供电的取样器的研究人员可以用吸附管快速收集一升空气，并将其送到实验室进行分析。另一种方式是，将可移动式热解吸仪/ GC仪器用于现场的直接污染源采样。 当样品在高湿度区域收集时，两级吸附剂捕集和热解吸有效地消除了水分干扰，增强了样品流中极性化合物的分析。 （其他采集技术，如罐式取样，必须限制采样量以控制转移到GC的水量，这往往会降低灵敏度，并限制极性化合物的回收。） 热解吸系列产品 CDS 9300 单管热解吸的基础型号 阅读更多内容 CDS 9350 CDS 9350具有双管配置，支持连续实时空气监测。 阅读更多内容 CDS 7550S 单机72工位热解吸系统 阅读更多内容 采样设备 可选择双通道和四通道进行空气采样。 即将推出 CDS 9305 准实时采样热解吸系统 阅读更多内容 采样管活化仪 CDS单管和6管活化仪是您分析中的重要附件。 即将推出 CDS 7550 9300家族的自动进样器具有72个工位 ，提高了样品通量和效率。 阅读更多内容

CDS Analytical's cryo-mlll cryomill is a laboratory ball mill that is designed to homogenize polymer samples and microplastic samples cooled by liquid nitrogen. Home >> Products >> Pyrolysis >> Cryo-mill Pyrolysis Introduction Features Applications Parts & Options Downloads Cryo-mill Product Introduction Product Introduction Out of gallery Specifications: Grinding Technology: Max Frequency: Temperature Range: Capacity: Grinding Ball: Finish Powder (8 runs): Feed-in Sample Size: Weight: Dimension (W x H x D): Accessoires Included: Ball grinding, Vertical oscillation 70 Hz Liquid nitrogen (-196°C) 4 channel of 5 ml sample jar 9.6 mm zirconia 5 micron <8 mm 25 kg 260 mm x 470 mm x 380 mm Liquid nitrogen reservoir, metal tongs, 4X 5 ml titanium sample vessles, 5X 9.6 mm stainless steel grinding balls, sample rack and cover Summary A distinct advantage of analytical pyrolysis GC-MS (PY-GC-MS) in polymer analysis is a simplified sample preparation process by skipping the solvent extraction and concentration step. However, the challenging hurdle in the sample preparation for PY-GCMS is to homogenize the polymer samples, which would determine the reproducibility of the following sample runs. As the rule of thumb for PY-GC-MS, more homogenized samples would yield more reproducible data. Among various homogenizers, cryogenic ball mill has been proven to be a powerful tool in homogenizing thermally sensitive and elastic polymers. CDS Analytical has designed an economical and ready-to-use cryo-mill solution for such applications. Product Features Product Features Ball Grinding at -196 °C The CDS Analytical's cryo-mill adopts ball grinding technique and allows the sample to be pre-cooled by liquid nitrogen to -196 °C High Throughput The cryo-mill supports up to 4 sample jars. Each sample jar could host up to 5 grams of sample. Vertical Oscillation The cryo-mill could generate up to 70 Hz oscillation on the sample jar vertically to bring strong impact for effective sample grinding. 5 micron Final Fineness The sample jar could accommodate sample size less than 8 mm in diameter, and yield a final fineness up to 5 micron. Built-in Method The cryo-mill has a user-friendly interface with built-in method designed for Py-GC-MS applications. Safety First The cryo-mill has multiple safety features built-in, including an automated locking mechanism when the cryo-mill is not balanced.
