Technical parameters of naculomb breath analyzer
Product model: sunvou-ca2122
Product Name: naculomb breath analyzer
Application: (1) determination of exhaled NO; (2) Exhaled CO measurement (optional)
Technical specifications and requirements:
1. sampling
Sampling method: online direct sampling by the instrument (it needs to be completed at one go, suitable for patients over 4 years old);
*The sampler can collect the air bag offline (it can exhale for many times, which is suitable for the patients with online test difficulties and wards);
*Moisture collection to the air bag (can exhale freely, suitable for patients under 4 years old and severe patients);
*On line direct test of nasal exhalation;
(multiple sampling methods are suitable for any subject)
Sampling requirements: exhale the gas in the body first, then inhale through the built-in no filter of the instrument, and then exhale for sampling;
Expiratory pressure: >5cm water column;
Exhalation time: 10s (adult), 6S (child) or other time at the customer's option;
*Expiratory flow rate: 50ml/s, 200ml/s or other flow rates can be selected by the customer, and the concentration of no in bronchi and alveoli can be tested in sections;
*Expiratory sampling volume: 30ml;
Quality control: the instrument automatically monitors and prompts the test status, including inspiratory and expiratory flow rates, pressure and time, to ensure the accuracy and repeatability of sampling;
2. analysis
Performance index: test range: 0ppb - 3000ppb;
Analysis time ≤ 1 - 2 minutes;
Lower detection limit: 3 ppb;
Accuracy (comparison with standard valve): when the measured value is less than 50ppb, the error is less than ± 3ppb;
     when the measured value is ≥ 50ppb, the error is <± 10%;
Repeatability: the relative deviation CV shall be within 10%;
Linearity > 0.96 (correlation coefficient between measured value and standard gas distribution concentration within the range of 0-3000ppb);
Stability: the relative drift of the measurement interval within 2 hours, that is, the concentration change rate is less than ± 10%;
        (self calibration patented technology to ensure long-term stability)
