SUPERIORITY BY ADAPTATION
Automated
Sample Preparation:SPE –
GPC -
EVAporation
What
LCTech does
supplies innovative products and methods for the preparation and analysis of food, feed and environmental samples.
This system is designed for sample
preparation
mainly in food, feed and environmental laboratories,
but can be used in any lab in which GPC and/or any type of SPE columns are used for clean-up
FREESTYLE System -
Introduction
FREESTYLE –
The
Concept
EVAporation
SPE module
GPC module
FREESTYLE BASIC
FREESTYLE is
a system
which
is
based
on FREESTYLE BASIC and can
be
modified
with
modules
… in all imaginable combinations
Valves, syringe pump & others on top of y-axis (reduces dead volume in tubing)
FREESTYLE BASIC
FREESTYLE BASIC
xyz-robotic system
Flexbile robotic area; the appropriate „area“ can be created at any time by choosing the right racks
Rinsing port for needle
SPE Module
FREESTYLE Modules
SPE module as a 2nd z-axis
Universal manipulator for all standard SPE-/ Immuno affinity - (IAC) and Glass columns (e.g. LCTech columns) from 1 to 15 mL
Control unit for SPE module

Heart
of the
EVAporation
system:EVAporation chamber with sensors
Integrated vacuum pump, heater & electronical devices
Solvent recovery/ solvent recycling
Water for temperature control of the vacuum chamber
FREESTYLE –
adapted
to applications
Typical
combination
of different modules:
FREESTYLE BASIC + GPC + EVAporation:
For sample preparation (clean up) for pesticides / PAH and all other analytes in fatty matrices which have to be cleaned up before transfering to analytical instruments (eg. GC or LC).
Sample preparation for soil analysis
For a faster, reliable, more reproducible and more comfortable handling of such samples customer can choose a higher level of automation: FREESTYLE BASIC
with GPC module
for clean-up and EVAporation
module
FREESTYLE –
modified
for
applications
Typical
combination
of different modules:
FREESTYLE BASIC + SPE + EVAporation:
Automation of SPE – Handling in all kind of labs
For a faster, reliable, more reproducible and more comfortable handling of such samples customer can choose a higher level of automation: FREESTYLE BASIC
with SPE module
and EVAporation
module
The
unique
design
Sorry, FREESTYLE does
not
offer 50 or
more
platforms!
FREESTYLE has just one,
but you
can create this one
according your needs, your demands, at any
time
(no service or tools needed)
Racks can be individually positioned by hooking them into a toothed plate
frame
tray with vials
= rack
Frame can be used for different kinds of vials
Tray can be taken out of frame and prepared independently
Racks –
the
key
for
flexibility
for vials from 1.0 mL to 1000 mL (e.g. standard flasks, round bottom flasks, TurboVap, Büchi, test-tubes…)
racks can be cooled or heated
With protection for light sensitive samples
Vials and flasks can be sealed with septa
= You can choose between r.a. 30 different racks. And if you cannot find the appropriate rack we are sure that we can design it. Ask LCTech!
Racks –
the
key
for
flexibility
Powerful Software
Selection of individual
modules
or
combination
of different functions within a single method
(eg. SPE +EVA or GPC+EVA)
no hardware
changes
necessary!
Allows intuitive handling
and easy usage in daily routine
Indicates most of the logical failures done by the customer
choosing the wrong parameters
Always included in the purchase price of modules
FREESTYLE™
–
system
features
Integral system features
Extensive safety devices: - Possibility of immediate emergency stop
in case of danger or to prevent any dangerous situation
- Collisions recognition
with the possibility to proceed without loss of sample
All liquid containing tubing is located outside
the instrument, thus easily accessible and strictly separated from any electric wiring
Plausibility check
of software input
Software is always included
in the modules
Standards of development and production & safety guidelines
Developed and produced at highest level according to Machine Directive 2006/42/EC of the European Parliament and of the Council of 17 May 2006 on machinery, and amending Directive 95/16/EC (recast), including CE certification.
Developed and produced according to ISO 9001:2008.
CE labelled safety guidelines
FREESTYLE™ - Standards of production
For all standard SPE-cartridges/columns from 1 mL up to 15 mL
For all standard Immunoaffinity columns (1 mL/3 mL) IAC-columns can be stored in the rack sealed with a tight cap, so buffer does not flow out. IAC remains „fresh“ until you decide to use it
For glass columns for max. dimensions 105 x 17,5 ID (length x diameter)
SPE Module
SPE Module
Positive pressure
for all steps in which liquids are used
One rack
for all kind of columns: reusable adapters allow an easy to change and mixed setup for all kinds of columns
Columns can be moved to any
place in the robotic area
Standard three solvents, upgrade option up to six
solvents
Software allows the transfer of nearly any manual method straight to an automation
SPE Module & handling of SPE cartridges/SPE columns
SPE Module
Method
Development
Move next step from the basic tools with drag & drop to second column
The default button remains in the basic tools and can be choosen again
The collected steps in the second column build the method
Each button there can be individually changed and adopted by using the „bars“.
Application:determination
of the
Hydrocarbon
Oil Index in water/soil
according
to EN ISO 9377-2 (H53 Method)
For this very common routine application a special rack is used
36 samples can be handled in sequence
If desired FREESTYLE system (Evaporation module necessary) can evaporate them right away down to ≤
1.0 mL, sample can be
transferred in GC-Vial: ready for analysis
