CHEMICAL HAZARDS
WARNING
Learn about the chemicals which will be used in and near the equipment,
and observe the necessary precautions. Always wear appropriate personal
protective equipment, including face shield or goggles, gloves, and a
laboratory coat. Ensure that engineering controls (such as ventilation
systems) are operating properly. Do not mix waste borohydride with acids.
INJURY HAZARD FROM HYDRIDE EMISSIONS
WARNING
Please refer to the MSDS data sheets for metal hydrides which may be
present in the laboratory, such as AsH
Note regarding Poisonous Hydride Emissions: Since hydride generation is
adequate ventilation to prevent exposure to hazardous vapors or gases.
typically used to analyze trace levels (ppb levels) of potentially poisonous
metalloids and metals, it is highly unlikely that any dangerous accumulation of
such gases will occur in a lab environment at the typical sample consumption
rates of only a few mL/min or ng/min. The emissions of the plasma gases do
not contain any hydrides anymore and are no different from normal use of an
ICP. Higher levels of metal hydrides may occur if waste borohydride reagent is
accidentally mixed with waste solutions.
INJURY HAZARD FROM GLASSWARE
WARNING
Handling of glassware: Like with any glassware, it is important to avoid
stressing joints or applying pressure on connectors. Do not use tools to
tighten the fittings.
AVOID DRAIN OVERFLOW:
CAUTION
This is the most serious risk in terms of creating problems for the ICP/ICPMS
equipment. Because the sample and reagent flow rates are quite high (a few
mL/min) and the internal volume of the HGX-200 is limited, it takes only a few
minutes of improper drainage to cause the unit to overflow. This can extinguish
the ICP plasma and could lead to aggressive solutions flowing into the ICP torch
box area. This is particularly bad for units with the torch box mounted underneath
the RF load coil like on the THERMO ELEMENT2.
Every time you use the HGX-200, make absolutely sure that the drain is pumping
sufficiently. Change the pump tubing often (PHARMED® at least every 40 hours of
operation, PVC/Tygon® every 20 hours). This is especially true for users that use
this equipment only occasionally.

Equipment Startup Procedure

FIRST THING EVERY TIME:
Before you even think about starting the ICP, run the peristaltic pump
with sample and reagents flowing, and check the drainage!
