How to use Sodium Hexanesulfonate and what are the precautions
Sodium hexanesulfonate (sodium hexanesulfonate) is an ion pair reagent, which is often used in high performance liquid chromatography (HPLC), which can improve the separation effect of specific compounds. The method of use and precautions are as follows:
How to use
1. ** Mobile phase preparation **: According to the experimental requirements, an appropriate amount of sodium hexanesulfonate is dissolved in the mobile phase solvent. Generally speaking, its concentration is between 0.005 and 0.01 mol/L. For example, to separate a compound containing ionized groups, add 0.007 mol/L of sodium hexanesulfonate to the mobile phase of acetonitrile-water system. When dissolving, sufficient stirring or ultrasound is required to promote complete dissolution.
2. ** Column equilibrium **: Before injecting the sample, a mobile phase equilibrium column containing sodium hexanesulfonate is required. Usually at a flow rate of 0.5 - 1 mL/min, continue to rinse for 30 minutes to 1 hour until the baseline is stable to ensure that the column and mobile phase are in equilibrium.
3. ** Sample Handling and Injection **: Dissolve the sample to be analyzed in a suitable solvent to ensure that the sample concentration is appropriate to avoid excessive concentration and chromatographic peak tailing or overload. Then accurately absorb a certain volume of sample with a micro-injector and inject it into the HPLC system.
Precautions
1. ** Compatibility **: Be sure to confirm that sodium hexanesulfonate is compatible with the column and instrument components used before use. Some column stationary phases may interact with ion pair reagents, affecting column efficiency and service life. For example, some special bonded phases may not be suitable for mobile phases with high concentrations of sodium hexane sulfonate.
2. ** Concentration control **: Its concentration is too high, although it can enhance ion pair action, it may cause chromatographic peak broadening, column pressure increase, and increase the risk of contamination to instrument pipelines and detectors. If the concentration is too low, the expected separation effect cannot be achieved. Therefore, the optimal concentration needs to be determined by experimental optimization.
3. ** Rinse Maintenance **: After the experiment is completed, the column and system should be rinsed with a mobile phase that does not contain sodium hexanesulfonate in time. First use a mobile phase that does not contain this reagent in a similar ratio to the mobile phase containing ion-to-reagent, rinse at a flow rate of 0.5-1 mL/min for 30-60 minutes, and then gradually transition to pure organic solvent rinse to prevent sodium hexanesulfonate from remaining in the system and damaging the instrument and column.
4. ** Storage Conditions **: Sodium hexanesulfonate should be stored in a dry and cool place to avoid moisture and heat. Moisture may cause it to agglomerate, affecting the use effect and weighing accuracy.
Sodium Hexanesulfonate Quality Standards
Sodium+Hexanesulfonate is sodium hexane sulfonate, which is a chemical substance widely used in many fields. Its Quality Standard covers the following aspects:
First, it is related to the appearance and properties. Sodium hexane sulfonate is usually a white crystalline powder, which should be pure and free of impurities visible to the naked eye. This is the initial standard to ensure its quality. The purity of the appearance can directly reflect the level of the production process. If it contains impurities, it may have adverse effects on subsequent use.
Second, purity is critical. High-purity sodium hexane sulfonate is essential. Generally speaking, its purity needs to be above 98% or even higher. High purity can ensure that the substance can accurately exert the expected effect during use. If the purity is insufficient, impurities may interfere with relevant chemical reactions or experimental results. For example, in high-performance liquid chromatography analysis, low-purity sodium hexane sulfonate can cause problems such as baseline instability and abnormal peak shape.
Third, there are strict requirements for water content. An appropriate amount of water content can maintain the stability and performance of sodium hexane sulfonate. Usually, the water content is required to be controlled within a certain range, such as less than 0.5%. Excessive water may cause agglomeration, deliquescence, etc., which affects its use and shelf life.
Fourth, the content of heavy metals must be strictly controlled. Heavy metals such as lead and mercury, even if present in small amounts, may also cause harm during use, posing a threat to the environment and human health. Therefore, its heavy metal content needs to meet specific standards, often limited to very low concentrations, such as less than one part per million.
Finally, the pH range cannot be ignored. The pH value of sodium hexane sulfonate solution usually needs to be maintained in a specific range, such as 6.0 - 8.0, to ensure its chemical stability and performance. Exceeding this pH range may cause a chemical reaction of the substance, affecting its efficacy.
