On (b)(6) 2016, the customer reported high pressure alarms after placement of a new column with their g8 analyzer.Technical support (ts) advised the customer to remove the main power and replace the prefilter.With the prefilter removed, the pressure immediately increased to above 20 mega pascals (mpa).Also, when the waste valve was open, pressure remained at zero.However, when the valve closed and with the filter removed the high pressure alarm recurred.On (b)(6) 2016, a field service engineer (fse) was dispatched to address the reported event, which resulted in delayed reporting hba1c patient results.There was no indication of patient intervention or adverse health consequences due to the delay in reporting.
