Preventative Maintenance Service
For DSV systems that are functioning properly, an annual Preventative Maintenance (PM) Service is recommended to replace consumable parts before they fail and ensure continuous operation. The PM Service replaces syringe(s), syringe pump valve(s), injection valve rotor, gear pump gears/pistons/spring-clip, 7 micron gear pump filter, in-line 20 micron filter, 2 x 10 um reservoir filters, and the 2-way solenoid valve. There are several ways to options for purchasing the PM Service:

On-Site Repair
For a DSV system that is not functioning properly, a service engineer can come on-site to repair the instrument. During an initial troubleshooting phase, Houston MJ Associates will contact the customer, study the recent data files, and make a best effort over email/phone to pinpoint the root cause of the instrument failure. The service engineer can then transport the assumed correct parts to the site to repair the instrument. However, it is always possible that the root cause was misdiagnosed or that there were other problems that were not detected during the troubleshooting phase. In this case, the service engineer can attempt to repair the instrument with available parts on-site, or the service engineer may recommend shipping the instrument to Houston MJ Associates in order to be repaired properly.
Generally, we will recommend depot repair for a malfunctioning instrument, given that we have much better troubleshooting/repair capabilities at the depot. However, we do understand there are situations where it is very difficult to send the instrument to Houston MJ Associates, especially when the instrument is located outside of the United States. In these cases, we will make our best effort to successfully perform the repair on-site.

Depot Repair
For a DSV system that is not functioning properly, the instrument can be shipped to Houston MJ Associates for repair. If the customer does not have the original box and shipping foam, we can ship the customer an empty box with shipping foam so that the instrument is properly protected during shipping. If the customer needs a replacement instrument to handle the sample load while the malfunctioning instrument is being repaired, Houston MJ Associates has units available for short-term rental (minimum rental period of 1 month). At the depot, the malfunctioning instrument will be thoroughly inspected, diagnosed, repaired, and tested before being shipped back to the customer.
Premium Service Contract
Houston MJ Associates offers Premium Service Contracts on Y501's in good working order. The Premium Service Contract covers parts and labor over a period of one year for repairs on a single Y501. These repairs must be due to normal wear and tear, and not due to negligence or improper use of the machine.
Instrument Rental
Houston MJ Associates offers demo Y501 units for monthly rental, with a minimum rental period of 1 month. Generally, a rental unit can be shipped to the customer within one week. Renting is a good option for customers who have a unit out for repair. It also works for customers who would prefer to rent-to-own rather than buy the demo unit outright.
Spare Parts
For customers that prefer to do repairs and replacements by themselves, Houston MJ Associates offers a full range of spare parts. The most commonly requested spare parts are listed below, and please contact us for any parts you do not see here.
