Automation is the use of control
systems and information technologies to
reduce the need for human work in the
production of goods and services
Laboratory automation is the use of
instrument and specimen processing
equipment to perform clinical assay with
only minimal involvement the

 In
the early years of clinical laboratory
science--the 1920s, 1930s, and 1940s-tests and assays were performed
manually
 evolution of clinical laboratory
automation began in the late 1950s with
the development of flame photometry
and peripheral blood cell analysis

Technicon Autoanalyzer II
(AAII) systemPeristaltic Pump Module
AutoAnalyzer is an automated
analyzer using a special flow technique
named "continuous flow analysis (CFA)"
first made by the Technicon Corporation.
The instrument was invented 1957 by
Leonard Skeggs, PhD and
commercialized by Jack Whitehead's
Technicon Corporation. The first
applications were for clinical analysis,
but methods for industrial analysis soon
followed.
PATELKI
The first multichannel analyzer to perform eight determinations
simultaneously is described. The analyzer records directly on
calibrated paper, providing an “immediately usable form”. One
operator can perform 960 individual tests per day, equal to the
output expected per person in a month with manual techniques

analyzers allow 10
simultaneous
determinations
on 1 mL of serum at a
rate of 60 specimens per

 Continuous
Flow Analyzer
• Tubing flow of reagents and patients samples
 Flow
Injection Analyzer
• Centrifuge force to mix sample and reagents
 Dialyzer
module
• Separate testing cuvets for each test and
sample
• Random and/or irregular access
PATELKI
CONTINUOUS FLOW
 In
continuous flow analyzers,
• samples were aspirated into tubing to
introduce samples into a sample holder,
• bring in reagent,
• create a chemical reaction,
• and then pump the chromagen solution
into a flow-through cuvette for
spectrophotometric analysis.
PATELKI
• The major drawbacks that contributed to the eventual
demise of traditional continuous-flow analyzers in the
marketplace were significant carry-over problems and
wasteful
use of continuously flowing reagents.
PATELKI
 Continuous
flow is also used in some
spectrophotometric instruments in which
the chemical reaction occurs in one
reaction channel and then is rinsed out
and reused for the next sample, which may
be an entirely different chemical reaction.
PATELKI



Discrete aliquots of specimens and
reagents are pipetted into discrete
chambers in a rotor
The specimens are subsequently
analyzed in parallel by spinning the
rotor and using the resultant
centrifugal force to simultaneously
transfer and mix aliquots of specimens
and reagents into radially located
cuvets.
The rotary motion is then used to
move the cuvets through the optical
path of an optical system
PATELKI
 Discrete
analysis is the separation of each
sample and accompanying reagents in a
separate container.
 Discrete analyzers have the capability of
running multiple tests on one sample at a
time or multiple samples one test at a time.
 They are the most popular and versatile
analyzers and have almost completely
replaced continuous-flow and centrifugal
analyzers.
PATELKI
 Sample
reactions are kept discrete through
the use of separate reaction cuvettes, cells,
slides, or wells that are disposed of
following chemical analysis.
 This keeps sample and reaction carryover
to a minimum but increases the cost per
test due to disposable products.
