/pH-graph
for the illustration of the transformed Henderson-
Hasselbalch equation.
Alkaline Basic.
Analyzer Software mode for measuring, QC
measurement, system, calibration, commonly used
functions (quick access).
Arterial blood Blood taken from aorta.
AQC abbr. for AutoQC
AutoQC module The AutoQC module is a unit that
enables to perform quality control measurements
automatically.
AUTO-TROL PLUS B AutoQC material for controlling
BG, ISE, Glu, Lac, Urea/BUN, COOX/Bilirubin.
AUTO-TROL TS+ AutoQC material for controlling BG,
ISE, Glu, Lac, tHb/SO

.
Barcode Scanner PS2 hand scanner with integrated
decoder for an easy scanning of QC and electrode data,
patient or user identity and of desired alphanumeric
code.
BG abbr. for blood gas
BG measuring chamber The BG measuring chamber
and its electrodes are used to measure the pH value and
the blood gas values PO
2
and PCO

.
Bilirubin Is a yellow decomposition product of the red
blood pigment, hemoglobin, or more exactly, that of the
hemoglobin share.
Bottle compartment The bottle compartment
contains the waste water bottle (W Waste Container), the
S1 Rinse Solution bottle, the S2 Fluid Pack (contains the
solutions for BG and ISE) and the S3 Fluid Pack A
(contains the solutions for Glu, Lac and Urea/BUN -
cobas b 221<5/6> systems only).
In addition, the bottle compartment contains the
necessary docking mechanisms for fluid transport into or
out of the system.
Bottle tool To prevent spilling of the S1 solution. If the
facility is 3000 m above sea level or higher deaerate the
bottle before inserting to avoid splashing the S1 solution.
As well as to empty the W waste container.
BUN abbr. for blood urea nitrogen
Bypass nipple This is the connection between the
sample inlet path and the sample distributor.
Calibration for "Ready" The system automatically
selects a calibration which will transfer all selected
parame-ters to the state "Ready".
Contact clip The MSS cartridge in the Electrode holder
is pushed into the correct position by the contact clip,
thus anchoring it.
Clot Catcher Coagulate trap.
COMBITROL PLUS B QC material for controlling
BG, ISE, Glu, Lac, Urea/BUN, COOX/Bilirubin.
COMBITROL TS+ QC material for controlling BG,
ISE, Glu, Lac, Urea/BUN, COOX/Bilirubin.
COOX module The oximeter module is an optical
sensor module for determining the total hemoglobin
(tHb) and the hemoglobin derivatives oxyhemoglobin
(O
2
Hb), disoxyhemoglobin (HHb), carboxyhemoglobin
(COHb), methemoglobin (MetHb) and bilirubin.
Docking mechanism These mechanisms are very easy
to use and ensure optimum fluid transport.
Dummy electrode The dummy electrode is simply a
flow electrode and is only intended as a spacer and it has
no additional measuring functions.
