6.1.1 LocationoftheBPHG90
TheBPHG90mustbeinstalledindoorsandinalocationwherethereisnodangerthatit
canbeexposedtowaterorrain.Itcanbeinstalledclosetoawallorpossiblybelowadesk
(a20cmclearancemustbeobservedtotherearandabove,forthepropercoolingofthe
generator).ThepowerandEthernetconnectionsandthesupplyofH
2
gasaremadeonthe
rearoftheinstrument,whereasthepH
2
outletislocatedonthefront.
If the gas supply line is attached to the wall, the rear side of the generator must be
accessible to permit the easy attachment of the gas capillary tube supply line with a flat
wrench.
Thefrontpanelmustbeeasilyaccessibleandvisiblefortheoperationofthegenerator.
Thegeneratormustbeinstalledonaflatsurface.Onceinstalledthefrontwheelsmustbe
blocked and the instrument must not be moved afterwards without disconnecting and
reconnectingthegassupplyline.
6.1.2 HydrogenGasSupply
ThemostcriticalprovisionfortheBPHG90isthesupplyofpurehydrogenandpriortothe
installationoftheinstrument;provisionsforthesafedeliveryofhydrogengashavetobe
made.
Differentsourcesofhydrogengascanbeusedtosupplythegenerator:
1. An independent electrolytic hydrogen gas generator producing very pure hydrogen,
99.999%atsufficientpressure(P>6bar)andflow(≥0.4NL/min).
2. A pressurised cylinder (200 bar) located in a remote room or outside the building. The
cylinderwitharegulatorsuppliesametaldistributionlinemadeofstainlesssteelorcopper
tubing. The room where the BPHG 90 is installed is equipped with an H
2
gas outlet, a
manual stop valve, a pressure regulator, a pressure gauge, a purge valve, and a flow
limiter.Theoptionalhydrogensupplypanelcontainsallnecessaryprovisions(seesection
The Optional Hydrogen Gas Supply Panel [}29])
3. A pressurised cylinder (200 bar max.) with a suitable pressure regulator. The cylinder
mustbehandledandsecuredaccordingtheprevalentsafetyregulationsandconnectedto
theBPHG90inthesamewayasaremotecylinder(seepoint2above).
Theconnection betweenthe hydrogen supply and the BPHG 90is madeby meansof a
flexiblestainlesssteeltube(suppliedwithinstrument).
TheBPHGhydrogeninletpressuremustbebetween6and10bar.
6.2 InstallationProcedure
TheBPHG90willnormally be installedandtestedby a trainedBrukerserviceengineer.
Whenevertheinstrumentneedstobemovedtoanotherlocation,careshouldbetakento
followthecorrectinstallationprocedure.
