塑料-氧指数法测定燃烧行为-第一部分：导则详读

市面上有众多的新冠病毒qPCR检测试剂盒，本应用方案采用韩国Seegene公司的AllplexTM 2019-nCoV检测试剂盒在耶拿荧光定量PCR仪 qTOWER³G上进行样品检测，获得符合预期的结果。

Lipid profiling from complex lipid extracts can be a challenging and time consuming task. The high complexity of samples and co-elution of isobaric or isomeric compounds complicate the confident annotation of lipids. The presented 4D-Lipidomics workflow simplifies and streamlines the annotation and validation process using mobility-enhanced MS data.

Using Bruker’s Hysitron PI 88 SEM PicoIndenter equipped with tilt and rotation stages in conjunction with the QUANTAX EBSD system enables a more robust characterization of metallic materials by combining high resolution phase and grain orientation mapping capabilities with targeted nanomechanical property measurements. This combination could also be used to extend the scope of research related to other advanced textured, anisotropic, or multi-phase materials.

当称量仪器用于与质量控制相关的测量时，校准是必须定期执行的关键操作之一。国际上有许多标准规范都有这方面的要求，例如ISO9001、GMP法规以及与食品安全相关的一些标准。然而关于校准的定义、实施和校准的具体操作在全球范围内并没有一个完全统一的标准。在此，我们首先需要了解一下什么是校准，以及与调整和检定的区别。
