Malvern FAQ -- KB000012 Q: Why do I get high backgrounds when changing between using oil and then water？ A: What may be happening is that the water and residual oil in the unit is forming an emulsion, you need to flush thoroughly with a dispersant that is miscible in both water and oil such as IPA. It is also recommended that the windows are removed and cleaned as the oil may have coated the surface. 马尔文常见问题解答——KB000012号 问：当我用完油后改用水做分散介质，背景为什么会变高？ 答：可能发生的情况是：水和仪器中残留的油形成乳浊液，你需要用诸如IPA这种能与水和油都能混溶的介质进行彻底冲刷。由于油可能涂附在测量窗的表面，所以建议你拆下测量窗并进行清洗。
Malvern FAQ -- KB000005 Q:What is a good Background? A:Typically a good background should have a peak in the first detector of less than 150 units and slope away in an exponential manner. 马尔文常见问题解答——KB000005号 问：一个好背景是什么样的？ 答：典型地说，一个好的背景应为：在第一个检测器上有一个小于150的峰值信号，其它检测器的信号以指数方式依次减小
Malvern FAQ -- KB000075 Q: How do I find out which software version I have？ A: The standard way to find which software version you are currently running is to select Help from the main menu and then About. Your software version will then be displayed. 马尔文常见问题解答——KB000075号 问：如何查明我用的是哪个软件版本？ 答：找到你当前所用软件版本的标准方法是：从“主菜单”中选择“帮助”，再选择“关于”，你的软件版本就能显示出来。
Malvern FAQ -- KB000090 Q: What does obscuration mean？ A: This is a measure of the amount of sample added to the dispersant. It is usual to use an obscuration in the region of ten to twenty percent, although this is dependant upon the scattering properties of the particles. 马尔文常见问题解答——KB000090号 问：遮光度是什么意思？ 答：遮光度是表示分散介质中所含样品数量多少的一种度量。遮光度的取值范围依赖于颗粒的散射特性，我们通常所用遮光度的范围是百分之十到二十。
