Apologies for last week's column head
, which should have read 'Why addressing students matters.' Also: Glydelle Amon is president of Ateneo's Talakayan ng Bayan, and Dustin Abad, the Aisec Ateneo president.
First, a general introduction is given on the engineering of the problem, followed by the description of the technology used and the monitoring results, including stress of the main truss and column head
If organics are present in the mobile phase, these can accumulate on the column head
, leading to a build-up in back-pressure and damage to the column.
The column head
was drawn by Canadian artist Kai-Liis McInnes (www.kai-liisartstudio.com).
Adjust the column head
pressure within the appropriate range in Table 2.
The addition of the second pressure source regulates the splitting and maintains the engineered configuration independent of the column head
pressure and maintains a stable flow into the MS detector and olfactometry port.
The Varian SPI, particularly when operated in a cold on column mode (followed by a 200 [degrees] C/min heating ramp to as high as 400 [degrees] C, if necessary), guarantees a gentle 100% delivery of any analyte to the column head
With a flame ionization detector, the column outlet is at ambient pressure, whereas in a GCMS system, the column outlet pressure is at high vacuum, enabling decreased column head
pressure in order to maintain a specific column flow rate.
With pub column head
firmly screwed on during city centre walkabout, it's no wonder that one of Liverpool's newest alehouses, The Welkin, has hidden chameleon-like from the gaze since its opening in March this year.
