“UHPLC级”（Ultra-High-Performance Liquid Chromatography grade，超高效液相色谱级）指专为在超高压力、配合亚2μm（或表面多孔颗粒，SPP）色谱柱运行的UHPLC系统而定级的溶剂与流动相添加剂。与常规HPLC级相比，UHPLC级更强调极低微粒含量、极低非挥发残留、超低紫外（UV）背景，以及（通常）低痕量金属——以保护小粒径色谱柱，并在高灵敏度下获得干净、稳定的基线。供应商规格通常包括更严格的终滤孔径（通常0.1–0.2 μm；部分UHPLC系列标称0.1 ...
“UHPLC grade” (Ultra-High-Performance Liquid Chromatography grade) describes solvents and mobile-phase additives that are qualified specifically for UHPLC systems operating at very high pressures with sub-2 µm (or superficially porous, SPP) columns. Compared with regular HPLC grade, UHPLC grade ...
“for TLC”指某种试剂或材料适用于薄层色谱（TLC）——这是一种用于快速分离、纯度检查、定性鉴别与反应监测的平面色谱技术。实际应用中，“for TLC”常见于固定相与吸附剂（如硅胶G/GF254预制板或粉末）、配套材料/吸附剂（如硅藻土/硅藻岩、氧化铝G），以及衍生化/喷雾显色试剂（如DNPH〔二硝基苯肼〕溶液）。“for TLC”意味着在紫外下背景低、Rf（retardation ...
“for TLC” indicates a reagent or material is suitable for thin-layer chromatography (TLC)—the planar chromatography technique used for quick separations, purity checks, identity confirmation, and reaction monitoring. In practice, “for TLC” appears on stationary phases and sorbents (e.g., silica ...
基于质谱（LC–MS/MS）的蛋白组学已从发现研究扩展到定量、多位点修饰谱、靶向验证与大队列研究。与常规蛋白学实验相比，蛋白组学对“化学背景、离子抑制、样品损失与批次稳定”更为敏感：痕量盐/表面活性剂、塑化剂与聚合物溶出、金属离子污染、载体材料吸附以及消化效率波动，均会导致鉴定/定量波动、洗脱滞后或谱图抑制，从而影响跨批次与跨平台的数据可比性。 ...
LC–MS/MS–based proteomics has expanded from discovery research to quantitation, multi-site PTM profiling, targeted verification, and large-cohort studies. Compared with routine protein experiments, proteomics is more sensitive to chemical background, ion suppression, sample loss, and batch ...
流式细胞术以单细胞为分析单位，结合多激光/多通道荧光检测，可在短时间内完成高维度的细胞表型、功能与微环境测定。
Flow cytometry analyzes cells at the single-cell level and, with multi-laser/multi-channel fluorescence detection, can rapidly measure high-dimensional cell phenotypes, functions, and microenvironments.
In cell culture, single-use compounding systems, IVD components, and sterile tooling, terminal sterilization is often used as one of the risk-control measures.
