"I have found the Rigaku XRF staff to be remark­ably concerned about the function of the ZSX in my lab, as well as extremely respon­sive to my needs. On issues as simple as the location of a certain function in the software and as complex as the inevita­ble hardware problem, the staff is very willing to work with me. I fully expected to receive a lower level of support from Rigaku when my service contract expired. I am pleased that this didn't happen; they have responded to my questions and helped with every situation that has arisen. One XRF staff member... has even solved problems for me via telephone in airports between flights. I truly appreciate this quality of service."
