Filter media are available in several pore sizes, but 0.45 \u00b5m is the pore size used routinely for most studies at this time. Capsule or disk filters (table 5.2.1.A.1) are required routinely for most studies when filtering samples for trace-element analyses and are recommended when filtering samples for major-ion or other inorganic-constituent analyses.", "description": "8 p.", "publisher": { "@type": "Organization", "name": "U.S. Geological Survey" }, "author": [ { "@type": "Person", "name": "Skrobialowski, Stanley C. sski@usgs.gov", "givenName": "Stanley C.", "familyName": "Skrobialowski", "email": "sski@usgs.gov", "identifier": { "@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0001-8627-0279", "url": "https://orcid.org/0000-0001-8627-0279" }, "affiliation": [ { "@type": "Organization", "name": "Office of Water Quality", "url": "https://www.usgs.gov/mission-areas/water-resources" } ] } ], "funder": [ { "@type": "Organization", "name": "Office of Water Quality", "url": "https://www.usgs.gov/mission-areas/water-resources" } ] } }
