Provided are methods of using fluid loss control additives that comprise a water-soluble polymer with hydrophobic or hydrophilic modification. These thermoplastic polyamide molding materials are suitable for manufacturing molded parts and other semi-finished or finished parts, for example by extrusion, injection molding, pressing, direct process or direct compounding, respectively, wherein the compounded polyamide molding material is directly processed by injection molding or other shaping methods. The process includes generating an air current in at least one of the wires downstream of the first dewatering zone with the suction box. In this way a series of scan lines covering an area of the sample surface are rapidly collected, the length of each scan line being determined by oscillation amplitude. An electrospray emitter tip is in liquid communication with the liquid outlet of the liquid extraction surface sampling probe. A user review includes business information, a user opinion that includes at least a rating, and time information that relates to the time of user interaction with the business.
