目的和应用有一个基本的方法用于评估油漆和涂料在涂盖时的一致性，用刮刀搅拌液体并测量将其从液体拿出后的流动时间，运用这种方法，表面张力因素会使判定流动结束时间变得困难。使用301型粘度尺，表面张力的影响因素相对较低，流动结束时间可精确确定。粘度尺设计用于迅速测定用于喷涂和刷涂的油漆的粘度，一方面在稀释油漆时，它为实用的搅拌工具，另一方面它可作为测量物质粘度的装置。粘度尺使用和清洗都较简单，这使得它在实际运用中为一方便的仪器。测试原理粘度尺符合Rossmann标准。由防腐蚀弹簧钢片制成，有两个精确尺寸槽，槽的两个末端各有一个圆孔。此测量装置等同于一个投射到平面上的毛细管粘度计，槽代替毛细管，圆孔代替球体。两个不同宽度的槽等同于不同直径的毛细管，槽内的流动率取决于槽的宽度与液体的粘度和密度。使用301型粘度尺的流动时间和使用一个4 mm的DIN粘度杯的流动时间之间的关系如下：使用DIN粘度杯的流动时间大约是使用窄槽粘度尺的流动时间的5倍，或是使用宽槽粘度尺的流动时间的12倍。性能和测试评估将粘度尺浸到被测液体中，槽被完全盖住，而上端的圆孔保持在空气中。将粘度尺迅速从液体中提起，保持垂直，测量时间直到槽中的弯液到达下端圆孔。此点清晰可见，因为盖在圆孔上的薄膜将在此刻破裂。槽中的流动速度也会受到尺上余留物流动速度的影响。所以浸入深度应保持很精确。要取得精确的测量结果，作为额外的准备功夫，刮刀在进行测试前应先湿润。油漆包括挥发性溶剂的流动时间不应超过10秒，所以要将因溶剂挥发所引起的测量错误保持在最小值。槽的宽度为流动时间5秒而设计，窄槽用于测试喷涂粘度，宽槽用于刷涂粘度，槽有相应的标记。技术数据尺寸:180 mm× 20 mm× 0.5 mm（长宽高）净重：约0.015 kg

The SC-CSRS 300 suppressor is designed to make this conversion and provide linearity across as much as three orders of magnitude.Increased linearity for ammonium and aminesIncreased sensitivity for ammonium and aminesLow background and noiseConversion to and detection as fully dissociated methanesulfonic acidThe SC-CSRS should be used in industries where regulated methods require a linear response. A linear response increases accuracy at higher concentrations, and so requires fewer calibration check standards over the calibration curve. Reduced calibration requirements increase sample throughput for industries with high sample workloads such as the power generation industry.Method detection limits for Group I and II cations, ammonium, and amines using the SC-CSRS are equivalent to or better than those achieved using the CSRS 300.

This suppressor is ideally suited to ion-exclusion chromatography of organic acids and alcohols in complex or high-ionic-strength samples. It provides the following advantages:High-capacity and solvent compatible designOptimized for organic acid and alcohol analysis in complex or high-ionic-strength samplesLow detection limits, high signal-to-noise ratio, and excellent baseline stabilityFast startup and equilibrationThe Dionex ACRS-ICE 500 suppressor is used in chemical suppression mode with a tetrabutylammonium hydroxide (TBAOH) regenerant. Standard ion suppression converts analytes into their acid or base forms. The Dionex ACRS-ICE 500 suppressor increases analyte conductivity by forming the TBA salt of the weak acid analyte, which is more conductive than the partially ionized acid form of the analyte. The Dionex ACRS-ICE 500 suppressor removes the hydronium ion and any counterions of the analytes from the eluent stream and replaces them with tetrabutylammonium ion. This removal greatly reduces background conductivity. In addition, this mechanism forces the ionization of weak acid analytes, increasing sensitivity.

德国ERICHSEN301粘度尺测试原理： 粘度尺符合Rossmann标准。由防腐蚀弹簧钢片制成，有两个精确尺寸槽，槽的 两个末端各有一个圆孔。此测量装置等同于一个投射到平面上的毛细管粘度计，槽代替毛细管，圆孔代替球体。两个不同宽度的槽等同于不同直径的毛细管，槽内的流动率取决于槽的宽度与液体的粘度和密度。使用301型粘度尺的流动时间和使用一个4 mm的DIN粘度杯的流动时间之间的关系如下：使用DIN粘度杯的流动时间大约是使用窄槽粘度尺的流动时间的5倍，或是使用宽槽粘度尺的流动时间的12倍。应用： 使用301型粘度尺，表面张力的影响因素相对较低，流动结束时间可精确确定。粘度尺设计用于迅速测定用于喷涂和刷涂的油漆的粘度，一方面在稀释油漆时，它为实用的搅拌工具，另一方面它可作为测量物质粘度的装置。粘度尺使用和清洗都较简单，这使得它在实际运用中为一方便的仪器。301型粘度尺的性能： 将粘度尺浸到被测液体中，槽被完全盖住，而上端的圆孔保持在空气中。将粘度尺迅速从液体中提起，保持垂直，测量时间直到槽中的弯液到达下端圆孔。此点清晰可见，因为盖在圆孔上的薄膜将在此刻破裂。槽中的流动速度也会受到尺上余留物流动速度的影响。所以浸入深度应保持很精确。要取得精确的测量结果，作为额外的准备功夫，刮刀在进行测试前应先湿润。油漆包括挥发性溶剂的流动时间不应超过10秒，所以要将因溶剂挥发所引起的测量错误保持在最小值。槽的宽度为流动时间5秒而设计，窄槽用于测试喷涂粘度，宽槽用于刷涂粘度，槽有相应的标记。德国ERICHSEN301粘度尺技术数据 尺寸: 长: 180 mm 宽: 20 mm 高: 0.5 mm 净重： 约0.015 kg
