What is the part number for an ELS 2420 vapor trap bottle that can be used with dichloromethane? - WKB16193

ENVIRONMENT

• 2420 Evaporative Light Scattering Detector (ELSD)
• ACQUITY UPLC ELS

ANSWER

700002682 - ASSY, BOTTLE TRAP, 1000mL, 2420. This is the standard bottle trap used for all ELS detectors (see notes below). 

ADDITIONAL INFORMATION

Part 700000574 is the nitrogen trap bottle.

We have no list of the materials of construction. Nor do we have have direct knowledge of any customer running 100% methylene chloride (dichloromethane) in our detectors, so we cannot say with certainty that you will or will not have an issue with the trap bottle, which is Nalgene (HDPP). Chemical resistance charts on the Web state that damage may occur within seven days of use.The trap bottle should only collect vapor (less than 50 mL in a month of use) if the detector is run properly. No other option is available from Waters. You should probably consider a glass trap setup if you have seen degradation.
