Whether it's analytical instruments for research laboratories, or related instrument consumables, accessories, repairs, relocation, or leasing services, Nanjing Aikon can provide users with suitable solutions.Chromatographic Peak Issues Caused by Chromatography Columns1. Ghost Peaks or Carryover Contamination?System contamination causes most ghost peaks or carryover contamination issues. If the additional ghost peaks have a similar peak width to the sample chromatographic peaks (with similar retention times), the contaminant may have entered the column simultaneously with the sample. Potential sources of additional components include the injector (e.g., contaminants) or the sample itself. Impurities in solvents, sample vials, vial caps, and syringes are also possible sources. Analyzing the sample and blank solvent separately can help identify the source of contamination. If the ghost peaks are much wider than the sample chromatographic peaks, the contaminant likely existed in the column before the sample entered. Residual components from a previous interrupted sample run remain in the column and elute later during the sample run, resulting in broader peaks. Sometimes, multiple injections can lead to overlapping ghost peaks or hump-shaped elution, accompanied by baseline drift.Increasing the final temperature or extending the temperature programming time can reduce or eliminate ghost peaks. Additionally, performing a short column bake after each or several sample analyses can remove strongly retained compounds from the column, preventing adverse effects. Conducting a condensation test can determine whether contamination in the injector is causing carryover contamination or ghost peaks.2. Why Do Sample Peaks Appear in Blank Runs?This is related to sample preparation or system cleanliness. Replace the solvents used in sample preparation, blank preparation, and syringe washing vials. Use new syringes and septa. Remove and clean the split vent line. Run a blank temperature program without injection to observe whether the peaks are due to heating the column.3. Is It Normal for Standard and Sample Peaks to Widen with Increasing Retention Time?If the retention time does not change significantly but the peaks become wider and tailed, this indicates active sites in the system. If the widened peaks are symmetrical, it suggests normal column efficiency loss. If the peaks are fronting, it indicates column overload.4. Excessive Baseline Noise?5. Unstable or Erratic Baseline?6. Tailing Chromatographic Peaks? Contamination in the injector or column, or an uneven column cut. Cool down the injector, turn off the gas flow, and replace or clean injector components, including the liner and gold-plated seals. Remove the column and trim a section from the column inlet to eliminate residual non-volatile components, septum material, and graphite ferrule debris. The length trimmed can range from 1 foot to 1 meter or more, as needed. Using the correct column cutting tool is crucial; uneven cuts can cause sample adsorption. Thoroughly clean the injector before reinstalling any components. Solvent cleaning of the split vent line is recommended.When using splitless mode for analysis, excessively long splitless times can cause tailing. Commonly set times are 0.5 to 1 minute.Volume can also cause tailing. Ensure the column is properly installed in the detector and injector.If the same column length must be maintained, consider using an uncoated retention gap (a pre-column before the analytical column). The retention gap can be trimmed or replaced without losing column efficiency and can effectively extend the column's lifespan. When using a retention gap, ensure the connection between the retention gap and the analytical column is leak-free and does not adsorb samples.7. Split Peaks?8. Changes in Peak Size?9. Retention Time Changes?10. Loss of Resolution?Nanjing Aikon Scientific Instruments Co., Ltd. is such a trustworthy partner. Whether it's selecting second-hand analytical instruments, laboratory equipment, daily maintenance, or technical support, Nanjing Aikon Instruments will be your choice. more>

Company: Changzhou Jintan Jinfang Machinery Factory

Product Description: Benefit Analysis of Carding System Transformation I. Reduction in Labor Costs for Cleaning and Carding Processes: Taking a 10,000-spindle system (8-16 carding machines) as an example. Before transformation: 6 workers per shift for cleaning and carding, totaling 18 workers for three shifts; after transformation, only 2 workers per shift are needed, totaling 6 workers for three shifts. Assuming an annual salary, benefits, and insurance cost of 20,000 yuan per person, each set of cleaning and carding equipment saves 240,000 yuan in labor costs annually. II. Reduction in Electricity Expenses: Taking a 10,000-spindle system (8 carding machines) as an example: After transformation, the power consumption of machines such as the lap former (10.35kw×2), vibrating cotton box (3.4kw×2), and condenser (4kw×2) is eliminated, totaling 35.5kw. The added power consumption of machines like the cotton conveying fan (3.75kw) and feeding box (1.32kw×8) is 4.31kw. It is evident that the power consumption for the cleaning and carding processes per 10,000 spindles is reduced by 21.04kw. At an electricity price of 0.7 yuan/kwh, working 20 hours per day and 340 days per year, the annual electricity cost savings amount to approximately 100,000 yuan. (The more machines transformed, the greater the savings!) III. Reduction in Equipment, Material, and Other Loss Costs: After the transformation of the cleaning and carding system, the lap former—the machine most prone to malfunctions,最难调整, and with the highest number of faulty parts—is removed from the cleaning system. This correspondingly reduces maintenance costs and downtime. IV. Reduction in Workshop Dust Levels: Since the cleaning and carding system is connected by sealed pipelines from cleaning to carding, dust and fine impurities cannot escape outside the machines. According to tests by relevant experts, the dust content in workshops using the cleaning and carding system is reduced by 62.5% compared to traditional lap processes, significantly improving the working environment, making it more environmentally friendly and healthier. V. Improvement in Sliver Weight Uniformity Quality: Due to the use of advanced continuous feeding devices and automatic cotton supply boxes like FA178A in the process, the weight unevenness of the sliver is effectively ensured. Under normal workshop temperatures, even without an auto-leveling device, the external unevenness of the carded sliver can be controlled within 3.0%. If carding machines with auto-leveling are added, the external unevenness of the carded sliver can be controlled within 2.5%, fully matching the standards of mainstream cleaning and carding systems today. VI. Improvement in Operational Efficiency and Yield Rate: Due to the significant reduction in故障率 in the cleaning section after transformation, operational efficiency is ensured. The cleaning and carding system avoids the adhesion of cotton layers during unwinding and the waste cotton layers caused by lap splicing during卷 changes, thereby improving the yield rate by 1%.   more>
