Product Description:
The optical fiber of the coagulation analyzer plays an important role in the process of coagulation testing.
The coagulation analyzer is a medical device used to detect the
blood coagulation function. The optical fiber is mainly used in the
optical detection system. When the blood sample undergoes a
coagulation reaction during the testing process, there will be
changes in some optical properties (such as light scattering,
transmittance, etc.). The optical fiber can accurately conduct
optical signals and transmit the optical changes at the detection
site to the photodetector. In this way, the instrument can analyze
parameters such as the time and state of blood coagulation
according to the changes in the optical signals.
Like the optical fibers in other instruments, the optical fiber of
the coagulation analyzer also needs appropriate maintenance, such
as keeping the connectors of the optical fiber clean, preventing
the optical fiber from being bent or damaged, ensuring that the
optical signals can be transmitted accurately, and thus
guaranteeing the accuracy of the coagulation test results.
Polymerase chain reaction (PCR) instruments used for optical
detection, optical fibers play a crucial role.
Optical fibers are mainly used to connect the optical detection
components of PCR instruments, such as fluorescence detection
modules. During the PCR reaction process, as DNA amplification
occurs, fluorescently labeled substances will emit light at
specific wavelengths. Optical fibers can efficiently transmit these
optical signals to the photodetectors.
Its advantages include:
- High efficiency of signal transmission: It can transmit
fluorescence signals with low loss, ensuring that the detector
receives signals with sufficient intensity to accurately monitor
the situation of DNA amplification.
- Anti-interference ability: Due to its material and transmission
principle, optical fibers can effectively avoid external
electromagnetic interference, ensuring the purity of optical
signals and thus providing accurate detection results.
The optical fiber of the capillary electrophoresis instrument Product Overview
The following are the methods for cleaning and maintaining the optical fiber of the capillary electrophoresis instrument.
Cleaning Methods
- Cleaning of Connectors:
- Firstly, turn off the power of the instrument to ensure the
safety of operation. Use lint-free cotton swabs dipped in a small
amount of anhydrous ethanol or special optical fiber cleaner to
gently wipe the optical fiber connectors. Be careful and gentle
during the wiping process to avoid damaging the connectors.
- When wiping, wipe from the center of the connector towards the
outer circumference to prevent dust or impurities from being pushed
to the center of the connector and affecting the transmission of
optical signals.
- Cleaning of the Optical Fiber Surface:
- For light dust on the surface of the optical fiber, you can use a
clean and dry compressed air canister to blow away the dust.
- If there is more dust or some stains, you can use a soft and
clean non-woven fabric dipped in a small amount of appropriate
cleaner to gently wipe along the direction of the optical fiber.
Maintenance Methods
- Proper Use and Placement:
- During the use process, avoid excessive bending or twisting of
the optical fiber. Generally, there is a specified minimum bending
radius for the optical fiber, and you should operate according to
the requirements in the instrument manual.
- When the instrument is not in use, place the optical fiber
properly. It is best to coil it on a special optical fiber storage
device to avoid the optical fiber from being squeezed.
- Environmental Control:
- Keep the environment where the optical fiber is located clean and
minimize dust and corrosive gases as much as possible. You can
place the instrument in a clean laboratory or use an instrument
cover.
- Pay attention to the temperature and humidity of the environment
and avoid drastic changes in temperature and humidity to prevent
the optical fiber from being damaged due to thermal expansion and
contraction or moisture absorption.
- Regular Inspection:
- Regularly check whether the optical fiber connectors are loose.
If they are loose, tighten them in time.
- Check whether there are scratches, abrasions and other situations
on the surface of the optical fiber. If any problems are found,
evaluate the impact on performance and replace it if necessary.
