Sigma Series Pinnacle Control Software

By David Mazawa

You may have noticed something different about the Pinnacle. That is because the new Pinnacle Sigma series started shipping out mid June. Some improvements include fully ROHS compliant components, power cooling, USB connection, log file expansion, PEEK front end for reagent pumps, and lighter parts. It is important to note that new Pinnacle Control Software has been updated to support some of the new features.

Before installing the new software, make sure to export your Methods and Sequences. This will create a back up of all your Methods and Sequences. It is possible that your old Methods and Sequences will not transfer after installation of the new software. If this is the case, import your backup file.

You will notice that you need to install drivers with the new Pinnacle Control Software. The drivers are required to communicate with the USB port of the Sigma Series Pinnacle. We have replaced the RS-232 connection with USB. Make sure you follow the instructions included with the Pinnacle Control Software Installation CD.

After you have installed the new Pinnacle Control Software, make sure you double check the instrument configuration. It is possible that the default configuration of “No Connection to HPLC” will be loaded. After your methods and sequences are imported and your configuration is correct, you are ready to use the new Pinnacle Control Software.

The new Pinnacle Control Software includes pressure tests. These pressure tests should be used after a PM or when pump or valve seals have been replaced. You can pressure test individual pumps or pressure test the entire system. Make sure to follow the instructions presented by the Pinnacle Control Software. These tests can be found under Instrument then Maintenance.

The Pinnacle Control Software has expanded the log files. An extra day of data is collected and more detail is collected per log file. This will greatly help Pickering Laboratories Technical Support troubleshoot any problems you may have in the future.

Pickering Laboratories rolls out up-grade to Pinnacle PCX: New Sigma Series, by Mike Gottschalk


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 1.0.0.7 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.

Pickering continually improves the components and manufacturability of all our products to provide the best analytical tools in the industry.
