YH08 type 13C infrared spectrometerYH08
Medical equipment production enterprise license: Anhui food drug monitoring equipment production Xu 20160032
Medical equipment registration number: Anhui food drug supervision (quasi) 2014 2400117th
Communication connection between YH08 13C infrared spectrometer and computer:
YH08 13C infrared spectrometer interface of upper computer software:
2) volume: length * width * high =540 mm x 404 mm x 345 mm;
3) weight: about 18Kg;
4) the core composition of the measurement system:
A. optical system: narrowband bandpass interference filter module + sapphire window film + optical lens
B. infrared light source: a steady state blackbody radiation source with a gold-plated mirror, working temperature at 950 degrees C
C. sample pool: Aluminum
D. detector: PbSe infrared photosensitive detector
E. signal shear: chopper circuit breaker
F. signal acquisition: band-pass filter + analog to digital converter + Fast Fourier transform software
G. temperature control system: PID control mode using electric heating element and Peltier refrigeration element
H. injection system: micro electromagnetic valve and precision step motor control cylinder type injection system;
5) operation control mode: software control, through the software on the user's computer and the special man-machine interface.
6) the way of information output: the special human-machine interface on the user's computer, and the user printer.
7) the main technical indicators:
A. repeatability: average value of less than 0.3 (conditions: measurement of a group containing 3%CO2, DOB (%) =0 standard gas sample 10 times);
The accuracy of B.: the standard error is less than 0.3 (conditions: measurement of a group containing 3%CO2, DOB (%) =2 standard gas sample 10 times);
The concentration range of CO2 in C. samples: 1 ~ 6%;
D. sample volume: 120mL/ bag;
E. sample measurement time: the time to measure a patient's sample (including the bottom gas sample and sample gas sample each bag) is about 3 minutes, and the CO2 concentration in the sample is different, which will make the measurement time different.
F. preheating time: about 30 minutes, the preheating time may be shortened and extended automatically due to the influence of ambient temperature.
8) electrical safety:
Anti electric shock grade: class I
Overvoltage category: Class II
Grade of pollution: Grade 2<|@|>
The YH08 13C infrared spectrometer is suitable for clinical medical diagnosis. The variation of 13C abundance in the 13C urea breath test sample is more than that of the bottom gas 13C abundance, DOB (%) is used to determine whether the subjects are infected with Helicobacter pylori (Hp).
