Sovitelma kaasukromatografikolonnin kiinnittämiseksi Tämä keksintö koskee sovitelmaa kaasukromatografikolonnin kiinnittämiseksi.The present invention relates to an arrangement for attaching a gas chromatography column.
Eräässä tähän asti tunnetussa laitteessa on kolonni kiinnitetty kaasukromatografin kanteen, sen alapuolelle. Kansi on puolestaan nostettavissa ylös teleskooppi-maisen varren avulla. Ratkaisun haittapuolena on kuitenkin huonot kolonnin tarkastus- ja vaihto-olosuhteet, koska kolonnia käsiteltäessä joudutaan työskentelemään kan-sitason alapuolella. Kolonnin kiinnitykseen alhaalta ylöspäin liittyy aina kolonnin rikkoontumismahdollisuus ja toimenpide on muutenkin hankala suorittaa. Ratkaisun haittana on edelleen tarvittavien sähkö- ja kaasujohtojen, sekä muiden liittymien hankala sijoitus, koska te-leskooppimaisesti kymmeniä senttejä ylöspäin nouseva kansirakenne vetää mukanaan vähintäänkin yhtä pitkälti johtoja, joiden katkeaminen tai joutuminen asiattomaan paikkaan on mahdollista.In a hitherto known device, the column is attached to the cover of the gas chromatograph, below it. The lid, in turn, can be lifted by means of a telescopic arm. However, the disadvantage of the solution is the poor inspection and replacement conditions of the column, because when working with the column, it is necessary to work below the cover level. Attaching the column from the bottom up always involves the possibility of the column breaking and the operation is otherwise difficult to perform. A further disadvantage of the solution is the cumbersome placement of the necessary electricity and gas lines, as well as other connections, because the deck structure, which rises tens of centimeters upwards, attracts at least as much lines, which can be cut or placed in an inappropriate place.
Tämän keksinnön tarkoituksena on välttää tekniikan tasoa vaivaavat puutteet ja aikaansaada yksinkertainen ja toimintavarma, sekä työskentelyolosuhteiden suhteen edullinen sovitelma kolonnin kiinnittämiseksi.The object of the present invention is to avoid the drawbacks of the prior art and to provide a simple and reliable arrangement, as well as an advantageous working conditions, for fixing the column.
Keksinnölle on tunnusomaista, mitä päävaatimuksessa esitetään .The invention is characterized by what is stated in the main claim.
Keksintöä kuvataan seuraavassa tarkemmin viittaamalla oheisiin piirustuksiin, joissa kuvio 1 esittää keksinnön mukaista sovitelmaa sivukuvana ja 621 90 2 kuvio 2 esittää samaa sovitelmaa suoraan ylhäältä katsottuna .The invention will now be described in more detail with reference to the accompanying drawings, in which Figure 1 shows an arrangement according to the invention in a side view and Figure 2 shows the same arrangement directly from above.
Kuvioissa on viitenumerolla 1 merkitty itse kaasukroma-tografin runkoa, viitenumeron 2 merkitessä uunin kantta, joka on kiinnitetty runkoon saranoiden 3 avulla. Kuvioista voidaan selvästi havaita, että kolonni 4 on kiinnitetty suoraan kanteen 2. Kolonni siis nousee mukana, kun kansi avataan, jolloin se myös jäähtyy huoneen lämpötilassa nopeasti. Kolonni 4 on mahdollisesti kiinnitetty asennusta helpottavaan kehikkoon 5.In the figures, reference numeral 1 denotes the body of the gas chromatograph itself, reference numeral 2 denoting the lid of the furnace, which is fixed to the body by means of hinges 3. It can be clearly seen from the figures that the column 4 is attached directly to the lid 2. The column thus rises with it when the lid is opened, whereby it also cools down rapidly at room temperature. The column 4 is possibly attached to a frame 5 to facilitate installation.
Kansi 2 voi olla varustettu esimerkiksi sähköisellä tai hydraulisella sulkimella tai laitteella, jonka avulla on mahdollista hidastaa sulkeutumisnopeutta vapaasti suljettaessa, jottei kolonni vaurioituisi suljettaessa.The lid 2 can be provided, for example, with an electric or hydraulic shut-off device or a device, by means of which it is possible to slow down the closing speed when closing freely, so that the column is not damaged during closing.
Kaasuja varten olevat putket ja myös sähköiset kaapelit yms. on kiinnitetty kanteen 2.Pipes for gases and also electrical cables, etc. are attached to the cover 2.
Keksinnön mukaisen sovitelman etuina on edellä mainittujen lisäksi esimerkiksi se, että kolonni voidaan asentaa ja sitä huoltaa vapaassa tilassa ainakin lähes vaakasuorassa asennossa, jolloin käsittely sujuu nopeasti ja varmasti sekä rikkoontumisriski vähenee olennaisesti. Myös kaikkien liitäntöjen tekeminen reunastaan nivellettyyn kanteen on yksinkertaista, eikä ole vaaraa johtojen katkeamisesta tai joutumisesta asiattomaan paikkaan. Itsestään selvänä etuna sovitelmasta on, että uuni voidaan tehdä erittäin pienikokoiseksi, josta puolestaan seuraa tiettyjä käyttöteknisiä etuja.In addition to the above, the arrangement according to the invention has the advantage, for example, that the column can be installed and serviced in a free space at least in an almost horizontal position, whereby the handling is fast and safe and the risk of breakage is substantially reduced. Also, making all the connections to the edge-articulated cover is simple, and there is no risk of the wires being cut or misplaced. The obvious advantage of the arrangement is that the oven can be made very small, which in turn implies certain technical advantages.
