 DELTA Chromatography Data Systems
|
New !
... Updated for Windows Vista and Windows Seven.
Students
can use Delta 5.5 as a learning tool, just download and install the
demonstration version from the downloads page.
The demo version is
also useful to Delta owners as free software for reprocessing
previously collected chromatograms on PC's that don't have the data collection
hardware.
Delta 5.5 is an eighty
percent re-write of Delta 5.0, preserving only the fundamental Delta 5.0
calculation engine.
Delta 5.5 is modeled on Delta
5.0 for a number of reasons ...
|
 |
To ease the migration learning curve for Delta 5.0 users. |
|
|
Delta 5.5 is purposely designed as an interim step between Delta 5.0 and
Delta 6.0 and is available to Delta 5.0 users (who have compatible data
collection interfaces) at no charge ! (yes, that's right...free !!!). |
|
|
Having said that, we just couldn't release twelve months of very hard work
brandishing the tired old Delta 5.0 main menu ... so Welcome to the Delta 5.5
Main Menu !

For as long as mankind has toyed with mathematics the Greek
symbol DELTA (D) has been synonymous with change.
DELTA was originally chosen as the name for our data systems because of
mathematicians use of the DELTA symbol in integration ... the most fundamental
function of any chromatography data system. DELTA has now come to symbolize the
continual evolution DELTA has undergone since it's beginnings in 1984.
The design brief for Delta was to provide a data system
with a simple, intuitive interface while retaining the power required for
complex chromatography. This however was just the beginning; as Delta
developed we took the opportunity at every turn to incorporate features which
addressed common problems, many of which have in the past forced
chromatographers to export data from their chromatography systems to other
software packages in order to provide the special calculations and reports
required.
Delta was designed from the ground up to be easy for the
newcomer to ease into. You can collect your first chromatograms without having
to develop any methods using the simple Integrator Mode ... Its as simple as
selecting Run... Integrator, entering your chromatogram run time
in minutes plus a few other simple options, then click on the Run
button.
Any software user knows that it's all very well having a
program absolutely bristling with power, however you will probably never get to
use all of that power if your are forced to learn about every feature before
actually achieving anything. Delta was designed so that you can start with tiny
steps and build up to the level of expertise required to perform your analyses.
For instance Delta boasts a WYSIWYG report writer that sports sophisticated
calculated and conditional fields... but who wants to design reports before
getting their first results ? Nobody really, that's why Delta is supplied with
twenty default reports. If you don't specify a report Delta simply chooses the
most appropriate of the default reports according to your method settings. In
truth, most of our users never design their own reports ... but for those people
who need intelligent quality control reporting to flag unacceptable results with
customized messages, the power is waiting there for the time you need it.
Instead of a heavy monologue, we have chosen to provide a
quick overview of Delta's capabilities in the following bullet point list of
features. Click the show me buttons
to see a screen shot of the feature in action.

|
Collecting your first chromatograms is a snap using DELTA's
Integrator Mode.
|
|
|
Getting the peak detection
right is simple, just start the method editor's AutoSet feature, point at a
peak and some baseline and let DELTA do the rest. |
|
|
DELTA uses a
component table to identify and name peaks of interest. To create a
component table you just open a chromatogram containing all of your peaks of
interest and let the component table editor's AutoBuild
wizard create your component table for you. All you have to do is enter the
real peak names. |
|
|
Timed events allow peak
detection settings to be altered during integration as well as opening and
closing up to four relays during data collection (for solenoid valve control
etc.) |
|
|
You can use your method without
creating a sample sequence using Run...Method. |
|
|
Sample sequences can process up
to 99 samples per line. For those users who wish to change methods during a
run, you can specify a different method on each line of the sample sequence. |
|
|
To reprocess chromatograms
after a run has completed, simply alter the source
column in the sample sequence from Capture to
File, (you only have to edit one line, then click
All) then click Run. |
|
|
There is no need to print
reports during a run. After the run is complete, you can return to the
Run window then click Review
to see a list of all of the chromatograms collected during the run then
preview both the chromatograms and their reports on screen. You can tag
chromatograms you want printed and submit them as a batch, or print them one
at a time while previewing.
|
|
|
Interactive Graphics allows you
to graphically examine chromatograms and their integrations in detail. If
desired you can edit a chromatograms integration manually, then re-process
and review to see the altered results. |
|
|
The powerful overlay facility
allows overlaying of an unlimited number of chromatograms and includes trace
alignment and stretching facilities as well as subtract, add, multiply and
copy to clipboard as a Windows (tm) metafile. |
|
|
System suitability reports
allow you to keep an eye on the overall performance or your system and
detect trends towards column failure etc, before they become a problem.,
DELTA provides the option of British (BSP) or US (USP) calculations |
|
|
DELTA provides the ability for
the user to create custom report templates. Most users .use on of the many
supplied report templates and modify it by altering the report name, adding
the name of their organisation , adding additional items to be printed,
altering the number of decimals in some fields or adding calculated or
conditional fields that calculate new values based on information already
available. For instance DELTA's system suitability reports perform all of
the necessary calculations as well as detecting and flagging erroneous
conditions. One of the more common uses for the report writer capabilities
is in quality control where certain results are checked to ensure that they
are within acceptable bounds - flagging results that fall outside those
bounds. |

|
Context sensitive help down to
the field level is always at hand, just press F1
if you need help. |
|
|
DELTA export results
directly to it's built in Excel compatible spreadsheet for performing custom
calculations or merging with data from other sources. |
|
|
Power users can use DELTA's
powerful 'Calculated Components' to avoid having to export results to
spreadsheets for further calculations. In one case QC testing of LPG gas
samples for total octane; from trucks leaving a facility was reduced from a
two hour laboratory exercise to a 2.5 minute procedure performed by the
truck drivers who simply connected their gas bomb to a compact high speed
GC, entered their truck number, flicked a valve and subsequently had their
QC report in hand two minutes later as they left with their load. The time
and money saving to the company was enormous. |
|
|
The DELTA event log keeps track
of method changes and other important system events. If security has been
enabled the log will also tell you who made the changes as well as recording
user log on, log off etc. DELTA can be configured to purge the event log
automatically at regular intervals.
|
|
|
DELTA can optionally be
configured to automatically create data sub-directories on a daily, monthly
or yearly basis. These subdirectories are named using a user specified date
format allowing easy separation of work in regular intervals.
