Sebopeho sa thepa ea mekotla ena se phetha karolo ea bohlokoa ho boloka botšepehi le ho nepahala ha lisampole. Mekotla ena e entsoe ka thepa e ikhethileng e etselitsoeng ho sebetsana le litlhoko tse fapaneng tsa sampole ea khase, joalo ka ho se sebetse ha lik'hemik'hale, ho tšoarella, le ho hanyetsa mocheso. Ho utloisisa thepa ea lisebelisoa tsena ke habohlokoa bakeng sa ho khetha mokotla o loketseng oa sampling oa khase bakeng sa kopo leha e le efe.

Tedlar®: Thepa le Melemo

Ho tšoarella le ho hanyetsa lik'hemik'hale

Tedlar® e tsebahala haholo ka thepa ea eona e matla ea 'mele, e e etsa khetho e ratoang bakeng sa mekotla ea sampole ea khase. Thermoplastic fluoropolymer ena e fana ka khanyetso e ntle ea lik'hemik'hale le ho kenella ha mouoane o tlase, ho netefatsa hore likhase tse entsoeng sampuling ha li sebetse ka thepa ea mokotla. Mekotla ea Tedlar® e etsoa ka ho kopanya mocheso, ho kenyelletsang ho kopanya maqephe a mabeli ho pota-pota ho etsa sebaka se sireletsehileng.

Likopo le Meeli

Mekotla ea Tedlar® e loketse ho etsa sampole mefuta e fapaneng ea metsoako joalo ka li-non-polar hydrocarbons le likhase tse inert. Leha ho le joalo, li sebelisoa hamolemo ka lisampole tlas'a mongobo oa 2% ho thibela liketso tse mpe. Mekotla ena e khona ho mamella mocheso ho fihla ho 204⁰C ka nako e khuts'oane, leha boholo bo khothaletsoang bo ka ba 120⁰C bakeng sa tšebeliso ea nako e telele. Maemong a amanang le likhase tse chefo kapa tse tukang, ho ka 'na ha hlokahala mekhoa e meng ea ho thibela mollo ho netefatsa polokeho.

Mekotla ea Mehlala ea FEP: Bohloeki le Boiketlo

Tiisetso ea ho qetela ea Tšilafalo e Tlase

Fluorinated ethylene propylene (FEP) e tumme ka ho ba thepa e sa sebetseng ka ho fetisisa ea lik'hemik'hale e sebelisoang mekotleng ea sampole ea khase. Mekotla ea FEP e fana ka bohloeki bo phahameng ka ho fetesisa, e netefatsa hore ha ho na litšila kapa tšilafalo e tsoang ho thepa ea mokotla ka boeona, e etsa hore e be e loketseng lits'ebetso tse hlokang hore ho be le ppm e tlase haholo. Lintho tsena li etsa hore mekotla ea FEP e be khetho e ntle bakeng sa sampole ea monko le lits'ebetso tse hlakileng tsa tlhahlobo.

Ho khetha thepa e nepahetseng bakeng sa mokotla oa sampole ea khase hangata ho ipapisitse le litlhoko tse ikhethang tsa ts'ebeliso ea sampole, ho kenyeletsoa thepa ea lik'hemik'hale ea khase, maemo a tikoloho le likhaello tsa tekanyetso. Lisebelisoa tsena tse ling li fana ka likhetho tse eketsehileng ho fihlela litlhoko tse fapaneng tsa indasteri.

Karolo ea Lihokelo Mekotleng ea Sampling ea Khase

Ho netefatsa Botšepehi ba Mohlala

Moralo le sebopeho sa thepa ea likhokahanyo li phetha karolo ea bohlokoa ho ts'ehetsa botšepehi ba sampole nakong ea pokello le tlhahlobo. Lihokelo hangata li etsoa ho tsoa ho polytetrafluoroethylene e hloekileng (PTFE) ho thibela tšilafalo, ho netefatsa hore ke likhase tse reriloeng feela tse nkuoang le ho hlahlojoa.

Dikgetho tsa ho itlhophisa

Lifeme tsa China li fana ka likhetho tse fapaneng tsa likhokahanyo, ho kenyeletsoa tse peli- sebelisa lihokelo tsa polypropylene tse sebetsanang le lits'ebetso tse bobebe haholo. Lintho tsena tse ikamahanyang le maemo li lumella tlhahiso e ngata le kabo e akaretsang ea mekotla ea sampole ea khase e hlophisitsoeng ho fihlela litlhoko tse ikhethileng tsa mosebelisi, ho netefatsa ts'ebetso le katleho.

Ho Itloaetsa le ho Fetolana ha Mekotla ea Sampling ea Khase

Mekotla ea sampole ea khase e ka hlophisoa ho latela boholo, thepa, le mofuta oa sehokelo ho lumellana le litlhoko tse itseng tsa mosebelisi. Bokhoni ba ho hlahisa mekotla ea ho tloha ho 1 ho isa ho 250 litres, mme le ho feta ha e kōptjoa, e thusa lifeme ho phethahatsa liodara tse ngata bakeng sa lisebelisoa tse fapaneng tsa indasteri, ho tloha ho litlhahlobo tse nyenyane tsa laboratori ho isa ho merero e meholo ea tlhokomelo ea tikoloho.

Mehopolo ea ho Khetha Lisebelisoa tsa Sampling ea Khase

Indasteri ea sampole ea khase e fetohela mekhoeng ea tlhahiso e tsitsitseng haholoanyane. Sena se kenyelletsa tšebeliso ea lisebelisoa tse ka sebelisoang hape, tšebeliso e fokotsehileng ea matla ha ho etsoa tlhahiso, le ho amoheloa ha mekhoa ea eco-e botsoalle. Lifeme li ntse li tsoela pele ho hlahloba likhetho tsena tse tšoarellang ho fihlela maemo a tikoloho le litebello tsa bareki.

Kedun Fana ka Litharollo

Kedun e fana ka tharollo ea sampole ea khase ho fihlela litlhoko tse fapaneng tsa indasteri. Re fana ka mekotla ea sampuli ea khase e phahameng - ea boleng bo holimo e entsoeng ka tlasa ts'ebetso e thata ea taolo ea boleng lifemeng tsa rona tsa China. Mefuta ea rona e kenyelletsa mekotla e entsoeng ka thepa ea pele e kang Tedlar® le FEP, e nang le likhetho tse fapaneng tsa likhokahanyo ho netefatsa hore li lumellana le lits'ebetso tsa hau. Ka ho shebana le boqapi le khotsofalo ea bareki, Kedun e fana ka tharollo e sebetsang, e tšepahalang le e theko e tlase bakeng sa litlhoko tsohle tsa hau tsa sampole ea khase.
