The Elecsys 1010 Analyzer
1.2 The Elecsys 1010 Analyzer
The Elecsys 1010 analyzer is a fully automatic, run-oriented analyzer system for
determination of immunological tests using the
e
lectrochemiluminescent process. All components and reagents for routine
analysis are integrated in or on the analyzer.
Operation of the analyzer is simple and intuitive. The reagents are stable and can
be directly loaded onto the analyzer. The consistent use of bar-coded reagents
greatly reduces the need for time-consuming manual entries in the daily routine.
Additional automation can be achieved by connecting a laboratory EDP (host)
system.
ECL/Origen
You can use serum and plasma samples in primary tubes, Hitachi standard cups,
microcups or cups on primary sample tubes. Bar-coded sample tubes are
recognized. Two STAT positions for STAT samples are also available.
Results are produced either qualitatively or quantitatively depending on the test.
The typical test throughput is approximately 50 results per hour.

1.3 Reagents, Calibrators and Controls
The reagent packs have a special 2D
(two dimensional) bar code, which
allows fully automatic registration and
management of reagent information.
Manual input or additional monitoring is
not necessary. The ready-to-use, liquid
reagents are loaded into one of the six
positions on the sample/reagent disk.
Reagents are available for analysis
after their bar codes have been
scanned.
Reagents, Calibrators and Controls
The handling of calibrators and Roche Diagnostics controls corresponds to that of
reagents. Most calibrators are ready-to-use. Lyophilized controls and some
calibrators must be prepared and transferred into the appropriate container.
Calibrator and control information is stored on 2D bar code cards (see Chapter
1.3.7, Calibrator and Control Bar Code Cards).
V 3.0 – Reference Guide 1 - 5
Roche Diagnostics Elecsys® 1010 Immunoassay System
1.3.1 Reagent Kits (Reagent Packs)
Reagent packs are ready-to-use and
incorporate three bottles connected to
each other:
●
The white bottle with a transparent
lid contains suspended magnetic
microparticles that act as the carrier
material of the ruthenium-labeled
complex during measurement.
●
The black bottle with a gray lid
contains R1.
●
The black bottle with a black lid
contains R2.
The test application, calibration data,
control information, sample and reagent volumes, as well as special measurement
conditions are contained in the reagent bar code and therefore do not have to be
entered separately by the operator.
The following are examples of typical box labels for an Elecsys reagent kit. The
large label contains the intended use statement, storage temperature, contents
and catalog number of the kit. The smaller side box label contains the lot and
expiration date of the kit as well as a bar code number. This bar code number is
used for tracking purposes and is not used by the analyzer.

Reagents, Calibrators and Controls
1.3.2 Package Insert
Each reagent kit includes a package insert. This insert contains information
required to perform the assay. Detailed information is contained in the product
information sheet supplied separately.
1.3.3 Product Information Sheet
Each assay applied to this analyzer has a product information sheet that provides
general information about the assay. Data contained in the product information
sheets is more detailed than what is in the package insert. Instrument settings are
encoded in reagent bar codes and not entered by the operator. This type of
information, such as sample volume, reagent volume, etc., are found in the
overview section of the product information sheet.
Product information sheets can be obtained from Roche Diagnostics as required.
1.3.4 Calibrator and Control Kits
In most cases, calibrators and controls
for Elecsys reagents come packaged
separately.
Each kit contains either bar-coded
calibrator or bar-coded control vials
ready for use on the analyzer. Most
calibrators are in ready-to-use liquid
form and require no further action other
than to place them on the sample/
reagent disk when a calibration is
necessary.
A few of the calibrators and controls
are lyophilized in glass bottles and must be reconstituted before being transferred
into plastic bar coded-labeled vials. (Empty bar coded-labeled vials are packaged
in these kits with lyophilized calibrators and controls.) Reconstituted calibrators
and controls can be stored in the plastic vials after transfer.
Calibrators and controls also have color-coded caps to assist you in identification.
A white cap is a level one calibrator/control and a black cap is a level two
calibrator/control. In the course of the year 2000, black and white color-coded
caps for controls will be phased out in favor of beige/light brown (level one) and
caramel/dark brown (level two).
Calibrator and control bar code cards are packed with calibrator and control kits,
respectively (see Chapter 1.3.7, Calibrator and Control Bar Code Cards).
V 3.0 – Reference Guide 1 - 7
Roche Diagnostics Elecsys® 1010 Immunoassay System
1.3.5 Reagent Bar Code Labels
Reagent packs have a bar code label that
contains information required to run the assay.
This information includes:
●
test number
●
lot number
●
master calibration curve parameters
(e.g. Rodbard parameters)
●
instrument settings
●
calibrator lot numbers and target values
●
expiration date
●
calibration frequency
The following information can be identified on
each reagent bar code label:
kit catalog number
reagent pack number
reagent bar code number
kit lot number
expiration date.
The reagent bar code label is in a new format. The new symbology utilizes
portable data files (PDF) and is called PDF417. Traditional linear bar codes serve
as a link to a database that contains the appropriate information. PDF417 is a two
dimensional (2D), stacked bar code that contains an actual entire data record. The
large amount of data that can be encoded allows all instrument settings to be
included, as well as the master calibration curve and additional information for the
assay. It is from this master curve and from the operator 2-point calibration that
the analyzer derives the update of the master calibration curve. For further
information, refer to Chapter 6, Calibration.
“Every PDF417 symbol (bar code) contains two error detection codewords that are
used like the check digit in linear bar code symbologies to detect decode errors
and verify that all data have been read and decoded accurately. Additionally,
PDF417 provides error correction in the event that portions of symbol have been
damaged, destroyed or are unreadable.”
1
It is a combination of this error detection and error correction that ensures a
reliable bar code. If the bar code cannot be read and the reagent lot has been
previously used by the analyzer, the 15-digit number can be entered manually in
the software.

traditional linear bar code label that
contains an identifier to link it to information
encoded in the reagent bar code label and
the calibrator or the control bar code card
(see Chapters 1.3.5 and 1.3.7).
1.3.7 Calibrator and Control Bar Code Cards
Each calibrator and control kit comes with one or two 2D bar code cards. The
following information is included but not limited to:
●
test number
●
calibrator/control lot number
●
control code (e.g., PCU1) (control card only)
●

Potential Hazards and Safety Precautions
1.4.2 Accident Prevention
Elecsys 1010 is a fully automatic analyzer designed according to the most up-todate safety requirements. This ensures the highest possible protection for the
operator from accidents and ensures correct functioning of the system.
Before using the Elecsys 1010, review the safety precautions described in this
chapter to avoid operational interruptions and to protect you from potential
hazards.
The following overview describes specific features for optimal analyzer and
operator protection.
Operator Training
Roche Diagnostics provides system training after which an operator not only
works with the Elecsys 1010 but is also familiar with the relevant safety aspects.
Stand-by Operation and Analyzer Preparation
(Stand-by = the analyzer has power, however, the motion functions of the
individual components are disabled). In Stand-by mode, the tips of the S/R and
sipper probe and the paddle of the microparticle mixer are stowed in their home
positions in the rinse stations. Therefore, the operator cannot be injured by the
probes.
The sample/reagent disk can be removed from the analyzer. Therefore, loading of
samples, reagent packs, calibrators and controls can either be performed on the
analyzer or away from the analyzer.
The consumable containers (CleanCell, ProCell, water and waste containers) are
replaced or refilled in Stand-by mode.
When all the necessary substances have been loaded on the analyzer, the scan
process can be started after closing the cover.
V 3.0 – Reference Guide 1 - 15
Roche Diagnostics Elecsys® 1010 Immunoassay System
Analyzer Cover
The analyzer cover must be closed prior to starting a run. A run cannot be started
when the cover is open. If the cover is opened during initialization, the analyzer
stops immediately.
If the cover is opened during a run, the analyzer moves the probes and
microparticle mixer to their home positions in the rinse stations within 2 seconds
to prevent accidental contact. As a result, the run is stopped.
CAUTION
Opening the analyzer cover during a run may cause results to be lost.
STOP
Key
Press the STOP key to stop all operations that Elecsys 1010 is performing as soon
as possible. This process is the same as that described for the analyzer cover.
STAT
Samples
STAT (Short Turn Around Time) samples can be placed on the analyzer in the
designated positions behind the control unit, even when the cover is closed and a
run is being performed. Contact with the probes or microparticle mixer is not
possible. To load STAT samples, the drawer is pulled forward to expose the STAT
positions. There is a mechanical lock present when access is not permitted.

Roche Diagnostics Elecsys® 1010 Immunoassay System
STAT
Sample Positions
The control unit is designed like a
drawer, which when pulled out
provides access to the two STAT
positions. During a run, up to two
STAT samples at a time can be
loaded in primary tubes or when
using a special adapter (supplied) in
secondary cups.
Normally, access to both STAT
positions is always possible. When
the STAT key is pressed, the
requests for one or both STAT
samples can be entered.
When the STAT requests have been
confirmed, the control unit is locked into
position by the analyzer until all of the
requested tests have been pipetted.
The control unit is then immediately
unlocked so that further STAT samples
can be processed during a run.
Note
A power failure during the pipetting of the STAT samples may lock the control
unit. The locking device can be temporarily overridden by inserting a screwdriver
below the control unit.
