Titra-Stat/pH-Stat
titration system
The innovative Titra-Stat/pH-Stat
titration system, introduced by FMS, sets new industry standards in
speed, precision, and performance, producing high quality and
consistently reliable titration results and reduced downtime. This
versatile titration system offers fully programmable multi-step
titrations, real time plotting and automatic documentation of titration
data. The Titra-Stat System documents the
entire process and produces high quality and reliable results throughout
the entire reaction sequence. The system can be
monitored and controlled from any remote location using a standard phone
line. The Titra-Stat has many
applications such as enzyme hydrolysis, fixed or stepped pH
crystallizations and extractions, and pH control of chemical reaction
bath.

PRINCIPLE
OF OPERATION
|
|
pH-Stat Technique
pH-Stat
is a powerful technique which maintains a constant pH as hydrogen ions
are released or consumed during the reaction. The basic principles behind
pH-Stat are as follows:
- The pH of a reaction is
measured continuously.
- Any deviation in pH from the set pH-Stat value is quickly compensated by reagent addition.
- The speed and the volume of reagent addition is measured continuously and controlled with a wide
range of flow rates to match the reaction rate.
- The temperature of the reaction is continuously
measured and the pH compensated accordingly.
The pH-Stat is not limited
to reactions using pH measurement and adjustment. The reactions involving
metal ions or redox can be
controlled and monitored using Ion-Selective or redox electrodes.

|
High Speed pH Control
The Titra-Stat
allows you to program flow rate ranges from 0.02
to 1000 ml /minutes with the same basic unit. Combining the patented flow
controller with dynamic control has enabled Titra-Stat
to contol the pH set point with superior speed
and accuracy and minimum over shooting. Higher flowrate
pumps are available for large scale titration.
For details consult FMS.

|
Real Time Plotting of pH,Temperature
and Reaction Rate
During the pH-stat run, the
real time curve of pH value, temperature and reaction rate (dispensed
volume) are plotted continuously as fast as every 0.5 second.
This feature of the Titra-Stat keeps the
operator fully informed about the pH, temperature and reaction process.
|
|
Atomatic
Documentation, Review & Data Compression
The Titra-Stat
can capture and save the titration and temperature data every 0.5 second
in a data file. The saved data can be reviewed and
compressed up to 1000 times. The Titra-Stat
allows you to display, review and print the results of the run or a
compressed summary and to analyze trends. The report feature allows you
to print the results in graph and tabloid form with automatic date, time,
title, file name, and the associated titration program.
|
|
Graphs and Tables
The titration data,
reaction rate, temperature and pump speed curves can be
superimposed on one screen. The Titra-Stat
allows you to review the saved data from up to four runs on the review
screen all at once.
|
|
Remote Monitoring & Control (RMC)
The Titra-Stat
is the first generation of Remote Monitoring & Control systems
offered by FMS. The optional RMC package enables the user to monitor and
control the Titra-Stat system from a remote
location using a laptop computer and a standard phone line. The RMC
allows the user to monitor pH, temperature, reaction rates, edit
programs, review data files, and change parameters such as pH set points,
the speed of titrant addition, and maximum
volume/time of titration.
|
|
Multiple Stepped pH Control Points
With Titra-Stat you can
program thousands of different pH set points within one run. This allows
you enormous flexibility to control the pH with a flow rate range of 20 microliters/minute to 1 liter per minute.
|
|
Modularity & Expansion
The modular design of the Titra-Stat allows the system to be
expanded with additional pumps, electrodes, valves and other
devices. The Titra-Stat can
be expanded to be monitored and controlled from any remote
location.
|
|
Variety of Different Pump Heads
The Titra-Stat’s
modular pump head design allows you to choose the best size and type of
pump head for your primary process and to choose optional pump heads for
other processes. We offer a variety of different pump heads whose wetted
part materials include Teflon, ceramic, stainless steel, kynar and tygon. Pump heads
can be manually replaced in less than a minute.
|
|
Wide
Range
of Flow Rates
The Titra-Stat
allows you to program a range of flow rates from 0.020 to 1000 ml
/minutes with the same basic unit. You can configure multiple pH set
points to be controlled with different flow
rates. For large scale titrations, higher flowrate pumps are available. For details
consult FMS.
|
|
Temperature Compensated pH
The Temperature Compensated
pH menu option performs real time temperature compensation for pH values.
As the temperature of the reaction changes during the run, the Titra-Stat system monitors the temperature as often
as 0.5 seconds and immediately corrects the pH
value.
|
|
Works With Strong Acids & Base
By changing pump heads, the
same titration system can be used for strong
acid or strong base titrations. FMS 's wide menu
of pumphead materials allows you to use any
kind of organic as well as non organic reagents.

Continuous Flow (No Buret)
With the Titra-Stat’s patented pump controller
you can set the volume that suits your reaction size. It can be set from
1 ml to thousands of liters without interrupting the reaction process for
buret refilling. The pump is accurate and can be easily calibrated.
|
|
Real Time Control
With the Titra-Stat real time control panel, you can adjust
parameters such as:
- Set
pH control point
- Proportional Range
- Duration
time of titration period
- Flow
Rate
This
feature allows you to optimize your parameters during runtime. In
addition, you can save the program and output for future reference.
|
|
Production Scale-Up
The Titra-Stat
allows the transition from small laboratory scale to production scale
titration to be as easy as replacing a pump head module. This feature of Titra-Stat saves money and makes the process
development, and scale up to production scale very economical.
