The Pinnacle PCX Delta Series post-column derivatization instrument was first introduced in January 2005 to replace the PCX 5200 instrument. The Pinnacle PCX introduction brought new technologies to post-column systems including programmable temperature gradient column oven, inert flow path, reactor coil cartridge switching system, computer controlled software among others.
With the inclusion of the column temperature gradient feature, our amino acid analysis time for hydrolysates was reduced by half from 60 minutes to 30 minutes. In addition to improved analysis speed the ability to change reactor volumes easily made the Pinnacle PCX ideal for method development and application switching.
The development team at Pickering has been working behind the scenes to improve and expand the advantages of the Pinnacle PCX. Now with the confluence of several new features and improvements a complete series up-grade is occurring to the Sigma Series.
Notable improvement highlights:
Fully ROHS compliant – the European Union directive to eliminate toxic compounds in electronic equipment.
Power cooling – additional fans and air ducts have been developed to speed airflow in the column oven for faster cooling.
USB connection to PC – in addition to the Ethernet and relay connections USB has been added.
Pinnacle PCX Software version 220.127.116.11 includes 4 day log files for over the weekend log files, timer algorithm that runs independent of the system clock in the PC.
PEEK Front end on the pumps to prevent corrosion.
Injected composite parts – Column oven door and instrument base are 50 % lighter – saving on shipping costs.
Best of all the work flow of all methods are unaffected and migration of existing methods to the new Sigma series is seamless.
