• Choosing an HPLC Column Supplier

    When choosing the correct HPLC column, you should consider the purpose of your separation. For example, if your aim is to separate two species, you need a column that has a high resolution. A column with a resolution of 1.5 or higher is the optimal choice. The length of the column should be based on the separation goal. Typically, a 15 cm column with a backpressure of 11 MPa is suitable.


    When selecting a column, it is important to know how the columns behave under various conditions. Read the specification sheet carefully and follow the recommended operating conditions. Sometimes you may need to use your column outside its recommended flow rate. In this case, you should monitor its performance carefully to ensure that it is operating at optimum efficiency.


    The type of column used in a particular application should also be considered. Some columns are not suitable for certain types of solvents. You may need a column that is suitable for a certain chromatography method. Some of these columns require multiple phases. For instance, an ideal HPLC system may require two or more different columns for different applications. Get helpful resources today!


    High-quality HPLC columns should meet the highest standards. For example, a 10-um column may be too big for your needs. Choosing a smaller diameter is a better option. It will give you a greater capacity. For example, a smaller internal diameter will result in better packing. A larger internal diameter may limit the pump flow rate, which can reduce the efficiency of the instrument. Know more about HPLC Column Supplier today!

    An HPLC column is expensive and requires proper maintenance. It must be optimized to maximize its efficiency. For example, it should be capable of extra-column band broadening. In addition, troubleshooting situations may involve the column, sample, mobile phases, and instrumentation. For size exclusion chromatography, the column should be cleaned properly.


    Certain SEC applications require surfactants to be used. This can affect the retention time and increase the resolution. For this reason, a dedicated SEC column is better suited for these types of tests. Read more about chromatography at https://en.wikipedia.org/wiki/High-performance_liquid_chromatography.

  • Chromatography Supplies

    Chromatography supplies are important to a wide range of laboratory procedures. They include the chromatography columns, electrospray tips, fittings, and syringes. Many of these products are manufactured by world-renowned manufacturers and meet stringent specifications. Choosing the right chromatography supplies is essential for accurate, reliable results.


    Chromatography supplies are used in the separation of non-volatile mixtures. For example, a solvent is drawn through a TLC chamber, where the non-volatile mixture is separated. This process is also known as thin layer chromatography. Chromatography supplies can be divided into two groups - the mobile phase and the stationary phase.


    Chromatography supplies can be obtained from a variety of sources. Some of these supplies include the chromatography columns and filters. The columns can be found in various sizes and materials. The size of the columns affects their sensitivity and loading capacity. Smaller columns have lower loading capacity. They are usually made from stainless steel, PEEK, or bonded silica.

    The chromatographic columns at https://www.chromtech.com/essential-list-of-chromatography-supplies used in the separation process can be either extruded or cut. This allows for a high degree of flexibility in the selection of chromatography supplies. The segments of the column are separated by using a solvent. The solvent is added to the top of the column, and the drugs are separated using a gradient of solvent. As the solvent moves down the column, the chromatographic materials are separated into their component elements.


    Chromatography is an important technique for separation of chemicals. The principle behind it is that the mixtures with similar characteristics will group together. Different compounds have different speeds and may behave differently when separated through the same process. Chromatography is very versatile and is used for many purposes. There are numerous industries that use chromatography.


    The chromatographic apparatus consists of a chromatographic column and a delivery tube. The column is typically made of glass. It is attached to a delivery tube that is 4 mm in diameter. The column is then packed with a pledget of fine glass wool. The mobile phase is applied to the packed column in a moderate stream.


    Chromatography supplies are necessary for a variety of applications, including food and beverage analysis. It is often used as a production-scale purification process to separate individual components from a mixture. It can also be used for determining the concentration of pharmaceuticals in pill formulations. The choice of phases and techniques is crucial to achieving the best results.


    Chromatography supplies are an important part of automated laboratory workflows. Quality consumables reduce instrument downtime, and minimize the need for repeat analyses. For this reason, it is important to choose a manufacturer with the highest quality standards. In addition, choose a company with a dedicated glassware division.

  • Choosing an HPLC Column Supplier

    HPLC columns are used in a wide variety of applications including analytical, forensic, and clinical testing labs. The pharmaceutical industry is the biggest driver of technological advancements in this area. High-throughput monolithic column technologies are expected to have the greatest economic impact. In order to increase throughput, LC columns have been improved in many ways.


    HPLC columns typically consist of high-purity particulate silica compressed into a stainless steel tubing. The smaller the particle size, the lower the diffusion distance and, thus, the higher the selectivity. As a result, decreasing particle size also increases backpressure. This is because pressure is inversely proportional to particle size. The decrease in particle size reduces interstitial voids and allows a compound to push through the column faster.


    HPLC column longevity is an important factor for chromatographers. Some chromatographers track column injections in their logbooks. However, many do not. In fact, many will simply install a HPLC column and leave it in their instrument until they notice a significant amount of tailing or resolution loss. Some will even document the time spent in a logbook. Read this article for more details!


    For optimal separation, the optimum column length is 15 cm. The longer column length provides more resolution, but this should be based on the separation objectives. In general, a 15-cm column operating at 11 Mpa backpressure is well within the operating range. There are several considerations in choosing the best column length for your application.

    In addition to the retention time, there are other important factors for HPLC analysis. While the lifespan of the columns is increasing, users still need seven new columns per instrument per year. This may be influenced by increased sample volumes or the procurement of improved columns. A few factors may also influence the decision to buy a new HPLC column.


    One important aspect to consider when choosing the right HPLC column is the type of column you want. Some columns have an inert matrix. A fast desalting SEC column should have a high pore volume and large pore size distribution. A dedicated SEC column is preferred for applications where additives are used. Ensure that the column you choose has an OCS sheet that specifies if it can handle the additives you are using.


    The next consideration is the separation parameters. You may need to modify your sample concentrations and method. The method will need further development if you want to achieve the best separation. For example, if you want to determine the concentration of a specific protein, you may use a monoclonal antibody as an internal standard. If not, you can also use NIST or USP standards for the same purpose.


    Another factor to consider is the manufacturer of the HPLC column. While a high-quality column will be expensive, a high-quality column will provide optimal separation performance. A good column supplier will also provide technical support and maintenance. Get more facts about chromatography at https://www.britannica.com/summary/chromatography.
