PeakSimple chromatography software combines quick learning, ease of use, and convenient powerful features for GC and HPLC and CE. PeakSimple is included in the price of every SRI Gas Chromatograph, HPLC and Data System. PeakSimple’s intuitive graphical functions and features are so user-friendly most operators can produce results almost immediately and without specific training. PeakSimple is packed with state of the art features like dragable retention time windows, seldom found in other data system software packages costing much more.

With PeakSimple, no hardware is installed in your computer, so you can use a small portable notebook instead of a full-sized computer. If you travel with your system or have limited bench space you will appreciate this. Multiple users can also connect their individual computers to the chromatograph without moving the data system hardware from computer to computer.

PeakSimple even includes built-in data validation, an extra-cost option on other systems. This allows you to replay and re-acquire a stored chromatogram over and over, to determine the reproducibility and precision of the entire system.

Of course, PeakSimple includes baseline subtraction, chromatogram overlay, DDE links, peak alarms, report generation, multi-level calibrations, data merge across channels, auto-sampler queue, batch reprocessing, and many other convenient features ( see following pages ). Software updates are free, and can be downloaded from our Website anytime.

Tech support is free, and you will be pleased to discover that most tech support calls are answered on the first ring by a knowledgeable technician ( no voice mail ).

Manual integration tools permit you to refine the integration method applied to any peak. The toolbox is available at the click of the mouse. Baseline projection may be "rubber-banded" from point to point, forced to a valley, dropped vertically, skimmed, etc.

Create customized autosampler sequences for liquid injections, purge and trap autosamplers, gas sampling valves, and stream selectors including unique pre-defined sample information, auto-calibration, and batch reprocessing of previously run samples.

Retention windows brackets are visible on-screen, and may be grabbed, dragged onto a peak, widened or narrowed. The component table is automatically updated when a retention window is graphically moved or modified.

Point at any location and a mouse click "zooms in" on your data for high precision visibility. Zoom to a particular channel or zoom to an expanded view for close examination of small peaks.

Program one or two SRI GC column ovens from ambient to 400º C with unlimited ramps and holds, .01 degree resolution, and even negative programming.

Any Windows supported color printer may be used to render chromatograms for stunning hard-copy. Print multiple chromatograms per page for easy detector-to-detector comparisons and paperwork consolidation. Print overlaid data in contrasting color and with adjustable line weight.

Overlay the data in any channel onto any other channel for retention time comparison or multi-detector correlation. Overlay Adjust feature lets you stretch and shift overlaid data to facilitate pattern matching.

Blank baseline subtraction is useful to compensate for baseline drift due to column bleed and temperature ramping. PeakSimple lets you subtract baselines in real time as data is collected or post run.

In addition to performing timed integration events, control up to eight external contact closure relay outputs to actuate sampling valves, autosamplers, solenoids, pumps, or any external device using TTL or relay contact closure triggers.

Calibrate peaks seven ways ( straight-line best fit, multi-line, quadratic, parabolic, etc. ) using single or averaged data at up to seven concentration levels. Statistics for evaluating line fit quality, modification date audit trail, and curve printout insure defensible results.

Link PeakSimple results to your DDE compatible spreadsheet or word processor ( Excel, Word, 123, etc. ). Analytical results are automatically transferred after every run, or can be accumulated within PeakSimple and copied as a block of data.

Program the carrier gas pressure with unlimited ramps and holds on SRI GCs equipped with electronic pressure control. Form binary HPLC gradients using SRI’s Model 210 HPLC pump.

PeakSimple’s Data-Logger Mode allows you to display a scaled and calibrated result in large numbers in place of the normal strip chart data presentation. This is especially useful when monitoring total hydrocarbons on one channel while performing a separation on another.

PeakSimple lets you merge the results from any channel or all channels into one report. This is handy when combining results from different detectors into single report for export to Excel or other data analysis programs.

PeakSimple allows up to three replicate calibration standards at each of seven concentration levels to be averaged when constructing calibration curves.

Noisy detector signals can be smoothed manually or automatically at the end of the run. Smoothing algorithms include Olympian, Moving Average, and Savitsky-Golay.

Print one, two, three, or four chromatograms side by side on one sheet of paper. When operating multiple detectors in series this makes data interpretation simpler. It also saves paper, time, and money.

PeakSimple will play back and re-acquire any chromatogram multiple times establishing the precision and accuracy of the data system using real data not "canned" chromatograms. Peak-Simple’s validation can be performed by the user anytime without extra hardware.
