Principle: Potentiometric
generated voltage difference between ion selective electrodes applied to a reference solution and to the sample
potentiometric difference between the sample and the reference solution is measured
E = E0 + 2.303 * RT/Nf * Log aiai = f * CiCi = Ion concentration

1. red blood cell lysis 2. reagent to convert all hemoglobin to the stable cyanmethemoglobin form

Principles
感應區
Diluent form a vortex
Cells are injected into the core of a sheath flow and confined to a narrow single-file stream by hydrodynamic focusing(15μm).
The cells are forced to pass through aperture in single file (one by one).
1. A distinguishing feature of blood cell types is
the diameter of the cells.( RBC 、 WBC 、 Platelet)
2. WBCs are classified according to the characteristics of their cytoplasm and nucleus.3. Cyanmethemoglobin can then be detected by a spectrophotometer set at 540 nm. The concentration of hemoglobin is then calculated from the optical density of the solution.

Specimen preparationSpecimen requirements
1. Use the EDTA anticoagulant 3 ml tubes.
2. Specimen volume: At least 1.5 ml
3. Specimen volume are less than 1.5mL(at least 100 μL):
Use small test tube containing a specimen and add
EDTA as an anti-coagulant (Manual mode).Preservation conditions
Samples can be analyzed within 4 hour(room temperature).
Interfering factors
Measurement results are affected by hemolysis, chyle and clotted blood.
DO NOT use clotted blood specimen.

Leica CM3050 S Cryostat for Frozen Sections
![Page 21: Introduction to Instruments FUJI DRI-CHEM 4000i Scil Vet Focus 5 Cryostat for Frozen Sections 2010/12/06 Speaker : Le-Shi Tsai.](https://reader030.fdocuments.in/reader030/viewer/2022013112/56649cb05503460f94975202/html5/thumbnails/21.jpg)
Frozen Tissue Processing
only use O.C.T as embedding medium
Hard tissue using a dedicated film
tissue process and cutting
fixing and embedding
freeze and slice
stain
mounting
observe it under a microscope
![Page 22: Introduction to Instruments FUJI DRI-CHEM 4000i Scil Vet Focus 5 Cryostat for Frozen Sections 2010/12/06 Speaker : Le-Shi Tsai.](https://reader030.fdocuments.in/reader030/viewer/2022013112/56649cb05503460f94975202/html5/thumbnails/22.jpg)
The advantage of Leica CM3050 S • It is ideal for undecalcified hard tissue :
1. can be set to any section thickness and
section automatically
2. with a dedicated film, can avoid the hard
tissue broken.• with rough-cut function• adjustable specimen temperature : In accordance with the type of specimen to select the appropriate
temperature.• adjustable cutting speed
