Acclaim RSLC 2.2 μm columns are available in four chemistries: high-density mo-nomeric C18 and C8, Polar-Advantage (PA), a polar-embedded reversed-phase (RP), and PolarAdvantage II (PA2), an amide-embedded chemistry which has excellent hydrolytic stability (pH 1.5 to 10). Selectivity is the most important factor in the success of a separation.

The PA material features a polar sulfonamide chemistry that provides very good hydrolytic stability and eliminates dewetting problems. The PA2 material features amide-embedded chemistry with excellent hydrolytic stability (pH 1.5 to 10).

Acclaim Rapid Separation Liquid Chromatography (RSLC) columns use 2 and 3 μm particles for fast separations. These columns, together with the UltiMate RSLC system, provide ultrafast, high efficiency LC separations. • Accelerate separations up to …

2023年2月12日 · 我是在做pa2.1的中间开始写这篇文章的，所以pa2.1可能写的比较简略，pa2的链接：https://nju-projectn.github.io/ics-pa-gitbook/ics2023/PA2.html。我使用的isa是riscv32（毕竟最简单hhh）。以下是正文. PA2.1

// statistic()这个函数用于记录关于模拟器性能和运行状态的信息，例如主机运行时间、总指令数和模拟频率。 这些信息对于性能分析和调试非常有用。 流程集中在调用 execute(n) 执行n条指令，因此来到 execute 函数中. Decode s; g_nr_guest_inst ++; 接下来看 exec_once 的流程： /*主要作用是执行一次指令，并更新PC的值。 它接收一个Decode结构体指针s和一个指令的PC值作为参数， 将PC值保存到s->pc和s->snpc中，然后调用isa_exec_once()执行指令，最后将执行后的动态 …

2024年11月29日 · 在药理学中，pA2的定义是能使激动剂提高到原来的2倍时，可产生与原来浓度相同效应所需的拮抗剂的摩尔浓度的负对数。 简而言之，pA2值越大，说明拮抗剂的作用越强。 pA2是拮抗参数（antagonism parameter）的一种表达方式，当有一定浓度的拮抗药存在时，激动剂增加2倍时才能达到原来效应，此时拮抗药的摩尔浓度的负对数即为pA2值。 pA2值是用于描述竞争性拮抗剂对药物效果抑制程度的一个参数。 它代表了在保持药物效果不变的情况下，所需 …
