carl roth Chromatographic Analyzer Classification

1). carl roth Gas Chromatograph

carl roth gas chromatograph mainly consists of a gas path system, injection system, separation system (chromatographic column), detection system, temperature control system, data processing, recording system, power supply, electronic circuits, and other components. It is suitable for volatile natural complex samples and samples requiring high detection sensitivity. It offers advantages such as low price, low maintenance and usage costs, ease of automation, and fast and accurate detection and analysis, playing an important role in many fields such as petroleum, chemical industry, and environment. Based on its principle, it can be divided into gas-liquid chromatography and gas-solid chromatography. Among them, gas-liquid chromatography is the mainstay of gas chromatographic analysis, suitable for various types of samples, as long as the boiling point of the separated components is not higher than 400°C, good separation and detection can be achieved. The characteristics of gas-solid chromatography are also very obvious; since there is basically no loss of stationary phase, the temperature usage range is very wide, and the column life is long; there are various adsorbents available for selection or use after modification, offering good separation selectivity, even capable of separating cis-trans stereoisomers. However, it should be noted that some adsorbents have catalytic activity at high temperatures and are not suitable for separating thermally unstable compounds.

2). carl roth High Performance Liquid Chromatograph

carl roth High Performance Liquid Chromatography (HPLC) is a new separation and analysis technology developed by combining modern high-pressure technology with traditional liquid chromatography methods, applying efficient column packings and high-sensitivity detectors. It uses liquid as the mobile phase and ultra-fine particle efficient stationary phase for separation. It mainly consists of a pumping system, injection system, separation system, detection system, and data processing system. It has advantages such as wide application range, high separation efficiency, fast speed, wide selection range of mobile phases, high sensitivity, reusable chromatographic columns, and easy collection of eluted components. According to the nature of the stationary phase, it can be divided into liquid-solid adsorption chromatography, liquid-liquid partition chromatography, ion chromatography, gel chromatography, and affinity chromatography. HPLC and gas chromatography do not differ significantly in basic theory; the major difference lies in the properties of the liquid versus gas used as the mobile phase.

3). carl roth Ion Chromatograph

carl roth ion chromatography separation principle mainly adopts ion exchange chromatography with suppressed conductivity detection. For most ionizable substances, ionization in solution produces conductivity, and by detecting their conductivity, their degree of ionization can be analyzed. It mainly consists of a mobile phase delivery system, injection system, separation system, suppression system, detection system, and additional devices for ion chromatography. Ion chromatography was initially applied in environmental monitoring for the analysis of trace anions and cations in water. With improvements in separation technology and detection levels, ion chromatography is now widely used in the power and energy industry, electronics industry, food and beverage industry, chemical industry, pharmaceutical industry, and life sciences, becoming an important branch of chromatographic analysis.

4). carl roth Supercritical Fluid Chromatograph

Carl carl Roth roth Supercritical fluid chromatography refers to substances that are neither gases nor liquids, whose physical properties lie between those of gases and liquids. Supercritical fluid chromatography is a chromatographic method that uses a supercritical fluid as the mobile phase and a solid adsorbent (such as silica gel) or polymers bonded to a carrier (or capillary wall) as the stationary phase. It mainly consists of standard packed columns, the 1082BHPLC system, back-pressure regulators, and pump head cooling systems. It is suitable for separating compounds ranging from highly polar organic acids and bases to low-polarity hydrocarbons. Compared with HPLC, it offers outstanding chiral compound separation capabilities, fast analysis and preparation speeds, low operating costs, broader applicability, and "green" environmental benefits, making it the optimal choice for separating chiral drugs and chiral compounds. It is increasingly applied in production and scientific research, with applications now covering pharmaceuticals, natural products, tobacco, fine chemicals, petrochemicals, forensic science, environmental monitoring, doping control, explosives, and various other fields. The main types include analytical supercritical fluid chromatographs, preparative supercritical fluid chromatographs, and hybrid supercritical fluid chromatographs.

5). carl roth Capillary Electrochromatograph

carl roth capillary electrochromatography achieves superior separation capability for trace complex biological and chemical system samples by applying a DC high-voltage electric field across both ends of a micro-bore column packed with fine particle liquid chromatography fillers. Capillary electrochromatography not only overcomes the peak broadening caused by uneven flow rates of pressure flow in HPLC, but also has no pressure drop within the column, making peak broadening related only to the solute diffusion coefficient, thereby obtaining high column efficiency close to the level of high-performance capillary electrophoresis. Thus, the theoretical plate number of capillary electrochromatography is far higher than that of HPLC. It is mainly used for the separation and analysis of aromatic compounds including polycyclic aromatic hydrocarbons, dyes, proteins, peptides, oligonucleotides, amino acids, enantiomers, etc., with increasing applications in drug analysis. It mainly includes forms such as packed column electrochromatography, open tubular column electrochromatography, and planar layer electrochromatography.

6). carl roth Thin Layer Scanning Chromatography

carl roth thin layer chromatography, also known as thin layer chromatography, is a chromatographic separation technique that uses support materials coated on support plates as the stationary phase and suitable solvents as the mobile phase to separate, identify, and quantify mixed samples. This is a particularly effective chromatographic method for rapidly separating substances such as fatty acids, steroids, amino acids, nucleotides, alkaloids, and others. A thin layer chromatography scanner is an instrument for quantitative detection and analysis of thin layer chromatography. There are two types of thin layer chromatography scanners on the market: traditional thin layer chromatography scanners and thin layer digital imaging analyzers.

7). carl roth Counter-Current Chromatograph

carl roth counter-current chromatography mainly consists of constant flow pumps, injection valves, detectors, separation columns, and other components. Unlike other chromatographic technologies, it does not require any solid carrier, thus avoiding adverse effects such as sample contamination, deactivation, denaturation, and irreversible adsorption caused by reactions between the solid phase carrier surface and the sample. At the same time, it has advantages such as wide application range, fast speed, large injection volume, low cost, and high recovery rate. Therefore, it has been widely applied in fields such as biology, medicine, food, materials, cosmetics, and environmental protection, especially valued in the separation and purification of active ingredients in natural products.
