The present disclosure describes a computer implemented method, a system, and a computer program product of controlling the purification of a macromolecule solution via real-time multi-angle light scattering.

The present invention relates to water feeder technical field, more particularly to a filter assembly and a portable water feeder. The filter assembly includes a tray and a filter piece; the tray comprises a bottom frame with a bottom plate and a supporting wall and a supporting ring, the supporting wall is arranged around its circumference of the bottom plate and extends upward, the supporting wall and the bottom plate are jointly surrounded to form a cavity, and the bottom plate is provided with a number of filter holes; the supporting ring is arranged above the bottom frame and is connected to its top of the supporting wall, the filter piece is placed in the cavity. When the filter assembly is used, water flows from the filter hole into the filter piece, and the filter assembly has the advantages of simple and compact structure.

A spacer for a body of a refrigerant tank—such as a modulator—in an automotive HVAC device is provided. In embodiments, the spacer is flexible to enable it to be inserted into the modulator, and expanded out against the walls of the modulator when released therein. The spacer inhibits a desiccant bag from contacting the inner wall of the modulator, namely the location where a hole (e.g., for an inlet or outlet) is provided. The spacer can be a cage that surrounds a lower portion of the desiccant bag. And end of the desiccant bag can wrap around a flange of the cage, and be attached to the flange by mechanical fastening (e.g., through a slot), or by welding, or other means.
