Distillation grade reagents generally refer to products that, during manufacturing, undergo one or more stages of distillation or redistillation (fractional distillation / redistillation) to remove low-boiling and high-boiling impurities, moisture, and certain reactive impurities. The result is ...
精馏级（Distillation grade）试剂通常是指：在生产过程中经过一至多次精馏/再蒸馏（fractional distillation / ...
“Suitable for Inorganic Trace Analysis” (also referred to as trace analysis grade/ultra-trace grade) is a suitability label used by suppliers for reagents intended to measure ultra-low levels of elements—typically metals and metalloids at the ppb–ppt level—by ICP-MS, ICP-OES, AAS, ion ...
“适用于无机痕量分析”（“痕量级/trace analysis grade”）是供应商面向超低含量元素测定（通常是金属/类金属元素，ppb–ppt级，适用ICP-MS、ICP-OES、AAS、离子色谱等）的试剂适用性标识。
“For DNA synthesis” is a functional grade formulated specifically for oligonucleotide (oligo) chemical synthesis and related enzymatic workflows. It is not merely “higher purity”; it prioritizes trace-level attributes that directly influence coupling reactions:
“用于DNA合成（for DNA synthesis）”是专门为寡核苷酸（oligo）化学合成/相关酶促流程准备的“功能性等级”。它不只是“更高纯度”，更强调对耦合反应有直接影响的微量指标：
In protein and nucleic-acid workflows, dialysis is commonly used for buffer exchange, desalting, and removal of small molecules (e.g., salts, denaturants, inhibitors). The sample and the dialysate are separated by a semipermeable membrane: small molecules diffuse into the dialysate while ...
在蛋白/核酸等生命科学实验中，透析（dialysis）常用于换缓冲液、脱盐、去除小分子（如盐、变性剂、抑制剂）等步骤。其原理是样品与透析液（dialysate）隔着半透膜，小分子自由扩散至透析液而大分子被保留，从而完成分离。选择合适的透析缓冲体系与配套化学品，是确保样品活性与后续实验成功的关键。 ...
UPLC（UltraPerformance LC）是Waters公司在2004年推出的超高效液相色谱技术名称并已注册商标，本质上对应行业常称的UHPLC（超高效液相色谱），两者在技术内涵上可视为同义：都基于亚2 ...
