In-situ filtration system for sampling in wastewater treatment plants and surface waters. Liquiline System CAT820 provides clear samples directly from your process. Equipped with Memosens technology, it simplifies commissioning and supports predictive maintenance. Easy cleaning of the special membrane surface and tool-free maintenance reduce
Sample Preparation Filter all water samples through a 0.2 μm Nalgene PES syringe filter. A 0.45 µm pore size filter of the same material should also be effective. Discard the first 300 μL of filtrate and filter the remainder directly into a clean plastic autosampler vial. Prepare aqueous soil extracts by adding 30 mL of 30 mM MSA to 3.0 g of

Filter membranes with a pore size of 0.45 µm are used for in-field sample preparation to investigate groundwater for dissolved heavy metals. Depending on the sample volume and the particulate load of suspended matter, so-called in-line filters can significantly streamline the sampling process, in contrast to the use of syringe filters.

Ideally, a 0.45-μm pore-size filter is required to determine DOC; however in practice, glass fiber filters with larger nominal pore sizes are often used. a. Filter apparatus: Glass, tetrafluoroethylene (TFE), stainless steel, acetyl resin, or other material that neither adsorbs nor leaches organic substances and is capable of holding the
the filter. Prove the filter does not remove stream components. Prove the stream does not adversely impact the filter. Identify, quantify, and assess impact of compounds that migrate from filter to process stream. Prove the filter removes bacteria from the stream per ASTM 838-05. Prove the filter’s bacterial retention capabilities with a

purpose of this study was to provide the comparison between titration and HPLC method in determination of vitamin C content in citrus fruits. Materials and Methods Sample preparation of titration method Sample and standard preparation and quantification of vitamin C in titration method was performed using the method described by Tee et al. (1996).
The sample volume was 400 µL. Both the Claristep ® 0.2 µm and 0.45 µm filters were used. Subjective determination of user comfort To compare the user comfort between the Claristep ® filtration system and syringe filters, the samples were additionally filtered with a syringe filter (RC; 0.45 µm pore size; 25 mm filter diameter).
Accommodating A Variety of Sample Types. Filter Vials are a single system which replaces HPLC Vials, HPLC Caps, Syringes, & Syringe Filters for the filtration of samples. In 15 seconds, Thomson Filter Vials allow for sample preparation of unfiltered samples to filtered samples in an autosampler-ready vial.
Water and acetonitrile were passed through polypropylene or PTFE syringe filters (as indicated in legend), then used 1:1 (v/v) to prepare the mobile phase for UHPLC. The system was run at 0.25 mL/min for 600 min with backpressure recorded every 50 min. DP represents total change in backpressure after 600 min.
