FAQs About AccQ-Tag Eluent A
1. What is the composition of AccQ-Tag Eluent A?
AccQ-Tag Eluent A is a proprietary solution specifically formulated to optimize the separation of amino acids when used in AccQ-Tag workflows. It is a buffer solution designed for use in high-performance liquid chromatography (HPLC) methods. The precise composition ensures consistent pH and ionic strength, which are critical for achieving reliable retention times and optimal resolution.
2. What are the recommended storage conditions for AccQ-Tag Eluent A?
AccQ-Tag Eluent A should be stored in a cool, dry place at a controlled temperature, typically between 2–8°C (36–46°F). Avoid exposure to direct sunlight, extreme heat, or freezing conditions, as these can affect its stability and performance. The container should be tightly sealed when not in use to prevent contamination or evaporation. Always check the expiration date and ensure proper storage to maintain the integrity of the eluent.
3. Is AccQ-Tag Eluent A compatible with other AccQ-Tag reagents?
Yes, AccQ-Tag Eluent A is fully compatible with other AccQ-Tag reagents, including derivatization kits and other eluents in the AccQ-Tag system. It is specifically designed to work in conjunction with the AccQ-Tag workflow, ensuring reliable amino acid separation and quantification. Using AccQ-Tag Eluent A alongside other components of the system guarantees optimal chromatographic performance, reproducibility, and consistency.
4. What is the shelf life of AccQ-Tag Eluent A?
The shelf life of AccQ-Tag Eluent A is typically indicated on the product label or certificate of analysis and is generally several months to a year when stored under recommended conditions. To ensure stability, store the eluent at 2–8°C, avoid repeated temperature fluctuations, and keep the container sealed tightly when not in use. Discard any eluent that appears cloudy, has precipitates, or is past its expiration date, as these may compromise analytical performance.
