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 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 in)
• 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 (5.9 in) 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 (0.59 in) 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 maximum exhaust flow could impact the sustainability of the plasma resulting in an error with the instrument function

Tips: If more ducting is needed, flexible ducting (p/n 410000400) is available in 1 m (39.3 in) sections.

Caution: The user is responsible for supplying the ductwork between the instrument and the lab extraction system.
