Exhaust Requirements for the 5000 Series ICP-OES

Answer

This Information Applies To: Agilent 5000 Series ICP-OES (5100/5110/5800/5900)

Issue

Correct ventilation is required to ensure proper function of the ICP-OES

Resolution 

The ICP-OES must be located under a flue that is vented by an exhaust fan and ducted to an external vent.

Caution: The exhaust system installation must comply with any rules and/or regulations that may be imposed by the local authorities responsible for control of facilities and fixtures in the work place

The exhaust system (flue, ducting, and external vent) requirements are:

• The ventilation ducting must have an ID of 150 mm (5.9 inches)
• Minimum flow: 2.5 m3 /min (90 ft3/min) at 2.4 m/s (7.7 ft/s)
• Maximum flow of 6.0 m3 /min (200 ft3/min) at 5.7 m/s (18.6 ft/s)
• Exhaust flow must be continuous as long as the plasma is on, and stable with a maximum fluctuation of ±5% of flow
• The fan control switch and running indicator lamp should be located in a position where the instrument operator can view the indicator and access the control switch
• Flexible ducting must be used for easy removal during instrument maintenance
• Ducting must be corrosion resistant, fire-proof and should be kept clear of fire alarms, sprinkler heads, and other heat-sensitive devices
• The external vent must be fitted with a back draft damper and the outlet location must be clear of doors, windows, and heater or air-conditioning units
• It is recommended to directly connect the exhaust ducting directly to the 150 mm diameter exhaust vent of the instrument
• If using an extraction hood, it is important to closely couple the exhaust vent of the instrument to the extraction port with a distance of no more than 1.5 cm (0.6 inches) above the exhaust outlet

Warning: The exhaust system must be on before the plasma is ignited otherwise damage to the instrument or injury to the operator may occur

Caution: Exceeding the exhaust maximum flow could impact the sustainability of the plasma resulting in an error with the instrument function

Tips: The component parts or a kit required for an exhaust system may be purchased from Agilent: External Inlet Duct Adaptor Kit p/n: G8010-68002

Caution: The customer is responsible for supplying the ductwork between the instrument and the lab extraction system, if not purchased with the instrument.  To allow for personal preferences, control gear switch and pilot light assemblies are not supplied by Agilent.
