2024年11月3日 · dls原理动态光散射法（dls）是测量散射光强度随时间涨落，通过计算自相关函数得到颗粒粒度分布的技术。 QELS与DLS的基本原理仪器结构QELS和DLS的仪器结构相似，都包括光源、样品池、检测器和数据处理系统。

Specific IOTA 240VAC DLS converter/chargers are supplied with a power cord (approx. 36 inch length) for connection to the AC input. Plug type on the cord is determined by the input voltage and ratings of the DLS. DLS-240-27-40 and DLS-240-54-20 models feature a standard IEC receptacle for inserting an AC power cord (not supplied).

The DLS-240-27-40 Converter/Charger converts nominal 216-264 AC voltage to 27.2 DC voltage for both DC load operation and 24V battery charging. As a power supply, the unit's tightly controlled regulation allows the user to operate a nominal 24VDC load up to 40 amps.

Dynamic light scattering (DLS), also known as photon correlation spectroscopy (PCS), is a commonly used characterization method for nanoparticles. The DLS particle size analyzer has the advantages of accuracy, rapidity, and good repeatability for the measurement of nanoparticles, emulsions, or suspensions.
