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.
