Waters 410 refractive index detectors are getting quite old now. Those early in the production run may be over 25 years old. However their specifications are still nearly identical new refractive index detectors, the Waters 2414 on fact offers a negligible improvement.Please see below:
Waters 2410 Drift 2.5 × 10–7 RIU/hr
Waters 2414 Drift 2.0 × 10–7 RIU/hr
Both the 410 and the 2410 are very low maintenance and have almost no consumable parts. We do replace the rubber feet and the cooling fan's filter media but these are trivial improvements. The main work in preparing a refractive index detector for sale is in it's testing. It may take several days for these detectors to reach a thermal equilibrium. Testing to make sure that the detector is able to maintain a stable baseline is critical and should it fail to do so there are several electronic components that can be replaced to bring the stability back within specification.
There are also several electronic components that routinely fail with these units. However if they are replaced during the rebuilding process the detector can have a new lease on life and can give reliable service again for many years. Repairing 410s is routine here at 2H2 but we are not the only used equipment vendor capable of servicing them. They use "through-the-hole' style of electronic components and even have several chips in sockets, making replacement simple. With surface mount electronic components, special tools and techniques are required to carry out a repair, to our knowledge our competitors do not have this capability. We don't really mean to be boastful however, in fact having one option for service is a very bad thing. Fortunately for the end user, this is not the case with the 410.
At one point all of our prices were posted online. Since the subprime fiasco of 2007 we have had an increasingly difficult time keeping our online prices up to date with the number of currencies that we normally quote in. Worse yet (for us) the prices of many instruments are in a state of flux. At this time(June 2010) we are in a buyer's market, this is an excellent time to buy used instrumentation, with prices approximately 10-15% lower then in 2007. Unfortunately we have had to switch from an online pricing setup to a quote-on-request one.
