Make sure that the column door is securely closed before starting operation.
Warning. The column heating block may become hotter than 75°C. For your safety, wear insulating gloves
when the column oven is warm.
Attention. La résistance chauffante de la colonne peut dépasser une température de 75°C. Pour votre sécurité,
prière de porter des gants isolants lorsque le four de la colonne est chaud.
Warnung! Der Heizblock des Säulenofens könnte heißer als 75°C werden. Für Ihre Sicherheit sollten Sie
isolierende Handschuhe tragen, wenn der Säulenofen warm ist.
Atención. El bloque calefactor de columnas puede estar por encima de 75°C. Para su seguridad use guantes
aislantes cuando el horno de columnas esté caliente.
Avvertimento. Il blocco della colonna potrá diventare molto caldo e superare ai 75°C. Per la sua protezione
usa guanti con insulazione per questa applicazione.
Reagent Pump
The reagent pump is a syringe pump. Refer to figure 2-4 and 2-8 (items 4 and 10). The syringe has a volume
of 70 ml. The flow rate can be programmed from 0.05 ml/min to 1.5 ml/min. Once programmed, the syringe
pump delivers at a constant speed. Since there is no need for constant refilling and dispensing (as with a
reciprocating pump), there is a very high flow precision that does not require external pulse dampening
features.
The syringe pump cylinder and head is made from a single piece of 99.9% Alumina for ruggedness and non-
reactivity. The piston surface is made from PEEK with an inert o-ring seal.
The pump contains a piston wash for extended seal life. The piston wash is automatically performed with the
movement of the piston.
For purposes of fast refill and flushing, the pump
can refill or dispense (to waste) at 55 ml/min.
