<\/span><\/h2>\n<p><span>Innsamling av grunnvannspr\u00f8ver, enten i <a href=\"https:\/\/www.solinst.com\/no\/produkter\/flernivasystemer\/403-cmt-flernivasystemer\/\" title=\"Solinst kontinuerlige flerkanalsr\u00f8r (CMT)\">Solinst Continuous Multichannel Tubing (CMT)<\/a> eller <a href=\"https:\/\/www.solinst.com\/no\/produkter\/flernivasystemer\/401-waterloo-flernivasystem\/\" title=\"Waterloo Multilevel Systems\">Waterloo Multilevel System<\/a>, m\u00e5 utf\u00f8res med utstyr som kan ta pr\u00f8ver i, eller gjennom, relativt smale r\u00f8r. Pr\u00f8vetakingsr\u00f8rene i Waterloo-systemet har enten 1\/2&#8243; ID (12 mm), 3\/8&#8243; ID (10 mm) eller 1\/4&#8243; ID (6 mm), avhengig av hvor mange soner som skal overv\u00e5kes. Disse \u00e5pne r\u00f8rene brukes vanligvis i stedet for dedikerte pneumatiske pumper i Waterloo-systemet n\u00e5r applikasjonen er relativt grunn og vannstanden h\u00f8y.  <\/span><\/p>\n<h2><span><br \/>Peristaltisk pumpe  <\/span><\/h2>\n<p><span>Enten man arbeider i \u00e5pne r\u00f8r i Waterloo System eller direkte i en CMT-kanal, er den vanligste m\u00e5ten \u00e5 ta en grunnvannspr\u00f8ve p\u00e5 enten \u00e5 bruke en <a href=\"https:\/\/www.solinst.com\/no\/produkter\/provetakere-for-grunnvann\/410-peristaltiske-pumper\/\" title=\"Peristaltisk pumpe\">peristaltisk pumpe<\/a> eller en minitreghetspumpe. Den peristaltiske pumpen tar en pr\u00f8ve hvis vannstanden er innenfor en estimert h\u00f8yde p\u00e5 7,6 m (25 fot) fra jordoverflaten ved havniv\u00e5. Det er viktig \u00e5 merke seg at for hver 1000 fot (300 m) \u00f8kning i h\u00f8yde over havet reduseres det barometriske trykket med ca. 1 fot i form av vann. Ved 300 meter over havet vil en peristaltisk pumpe derfor bare kunne trekke en pr\u00f8ve fra 7,3 meters h\u00f8yde, n\u00e5r man ogs\u00e5 tar hensyn til friksjon og effektivitetstap. Den peristaltiske pumpen brukes oftest med 6 mm (1\/4&#8243;) LDPE-slanger som senkes ned i kanalen p\u00e5 CMT-enheten, eller slanger fra Waterloo System-porten kan kobles direkte til silikonslangene p\u00e5 den peristaltiske pumpen. Selv om pumpen bare kan trekke vann hvis fallh\u00f8yden er over 7,6 m (25 fot) ved havniv\u00e5, kan inntaket til pumpeslangen plasseres mye dypere og trekke vann fra portinntaket, hvis \u00f8nskelig.     <\/span><\/p>\n<p><span><\/span><\/p>\n<h2><span>Mini treghetspumpe  <\/span><\/h2>\n<p><span>I situasjoner der vannstanden er for dyp for en peristaltisk pumpe, men ikke dypere enn ca. 50 meter under jordoverflaten, anbefales ofte den rimelige og brukervennlige minitreghetspumpen. Minitreghetspumpen er basert p\u00e5 samme prinsipp som alle andre treghetspumper, ved at den best\u00e5r av en polyetylenslange med en tilbakeslagsventil plassert i bunnen. Slangen senkes ned i br\u00f8nnen, og ved \u00e5 heve og senke systemet, vanligvis for h\u00e5nd og ca. 1 fot (24 mm), vandrer en puls eller slump med grunnvann opp i slangen og kan samles opp ved overflaten.    <\/span><\/p>\n<p><span>Ved pr\u00f8vetaking med CMT-systemet med minitreghetspumpen er slangen 1\/4&#8243; (6 mm) x 0,17&#8243; (4,3 mm) lavdensitetspolyetylen (LDPE) eller PTFE-f\u00f4ret LDPE kan brukes for bruksomr\u00e5der opp til 15 m (50 fot) dyp. P\u00e5 vanndyp fra 15 til 45 meter (50-150 fot) brukes ren PTFE for \u00e5 redusere friksjonseffektene p\u00e5 st\u00f8rre dyp. Andre slanger, som for eksempel Kynar, har ogs\u00e5 blitt testet, men de gir ingen fordeler og er dyrere. Tilbakeslagsventilen til minitreghetspumpen best\u00e5r av tre separate komponenter, to hule hylser i rustfritt st\u00e5l og en tilbakeslagskule i rustfritt st\u00e5l som er plassert mellom hylsene. Denne ventilenheten skyves inn i bunnen av 1\/4&#8243; (6 mm) slangen ved hjelp av et innsettingsverkt\u00f8y som ligner p\u00e5 en kort skrutrekker med smal diameter. Bunnen av hylsen har en krysshakedesign som forbedrer str\u00f8mningshastighetene, opp til ca. 150-200 ml\/min. Minitreghetspumpen kan ogs\u00e5 brukes til \u00e5 samle inn pr\u00f8ver fra \u00e5pne slanger som er installert i Waterloo-systemet.      <\/span><\/p>\n<h2><span><br \/>Pumper med dobbel ventil  <\/span><\/h2>\n<p><span>Pneumatiske (gassdrevne) pumper er det vanligste pr\u00f8vetakingsalternativet i Waterloo Multilevel System. <a href=\"https:\/\/www.solinst.com\/products\/groundwater-samplers\/408-double-valve-pumps\/\" title=\"Dobbel ventilpumpe (DVP)\">Dobbeltventilpumpen (DVP)<\/a> p\u00e5 16 mm (5\/8&#8243;) i diameter eller <a href=\"https:\/\/www.solinst.com\/products\/groundwater-samplers\/407-bladder-pumps\/\" title=\"Solinst Bl\u00e6repumper\">bl\u00e6repumpen<\/a> p\u00e5 24 mm (1&#8243;) i diameter er begge konstruert av rustfritt st\u00e5l og er bygget direkte p\u00e5 systemets pr\u00f8vetakingsporter. Disse pumpene gj\u00f8r det mulig \u00e5 ta grunnvannspr\u00f8ver fra dybder p\u00e5 opptil 300 meter (1000 fot). DVP velges ofte til dypere bruksomr\u00e5der og til pr\u00f8vetaking i grunnvann som kan inneholde finsedimenter, ettersom de er enklere \u00e5 rehabilitere, og pr\u00f8ver kan tas raskere fra dypet og i st\u00f8rre volum enn med bl\u00e6repumpen. Bl\u00e6repumper er fortsatt den foretrukne pumpen for grunnere bruksomr\u00e5der, opptil 150 meter, fordi de ikke kommer i kontakt med luft, og de anses derfor som ideelle for VOC-overv\u00e5king. DVP har blitt redesignet i mikroform for bruk i de trange kanalene i CMT-systemet. Dette pneumatiske alternativet er en s\u00e5rt tiltrengt utvikling for \u00e5 muliggj\u00f8re pr\u00f8vetaking i multikanalslangene p\u00e5 dyp st\u00f8rre enn 30 m (100 fot) og ogs\u00e5 for VOC-pr\u00f8vetaking p\u00e5 steder der treghets- og peristaltiske pumper ikke er egnet. Micro DVP er et levedyktig pr\u00f8vetakingsalternativ som kan pumpe med en hastighet p\u00e5 150 ml\/min n\u00e5r den plasseres i den smale CMT-kanalen. Micro Double Valve Pump er konstruert av rustfrie komponenter og koaksiale LDPE- eller PTFE-slanger. PTFE brukes p\u00e5 dyp st\u00f8rre enn 15 meter (50 fot) for \u00e5 redusere friksjonseffekten under installasjonen. En manifold p\u00e5 overflaten kobler pumpen til en drivgass (trykkluft\/N2-kilde), og pumpen betjenes enkelt ved hjelp av <a href=\"https:\/\/www.solinst.com\/products\/groundwater-samplers\/464-pneumatic-pump-control-units\/\" title=\"Solinst elektronisk kontrollenhet, modell 464\">Solinst Electronic Control Unit, modell 464<\/a>.           <\/span><\/p>\n<h2><span><br \/>Pr\u00f8vetaking av damp i CMT  <\/span><\/h2>\n<p><span>CMT-systemet er ideelt for pr\u00f8vetaking av gassdamp. CMT-systemet er konstruert med porter og plugger for \u00e5 tette kanalene p\u00e5 samme m\u00e5te som ved pr\u00f8vetaking av grunnvann. Den eneste ekstra komponenten er en ekstra plugg som plasseres p\u00e5 overflaten for \u00e5 tette toppen av pr\u00f8vetakingskanalen.
