Ultra trace nucleic acid analyzerIt is a high-precision instrument based on fluorescence detection or spectral absorption technology, mainly used for rapid and sensitive determination of nucleic acid (DNA/RNA) and protein content in biological samples. Its advantages include:

Trace sample detection: Only 0.5-2 μ L of sample is required, without dilution or pretreatment, suitable for precious or scarce samples.

High sensitivity and wide detection range:

Nucleic acid testing range: 10-4000 ng/μ L (dsDNA), which is tens of times larger than conventional UV spectrophotometers.

Protein detection range: 0.1-100 mg/mL, covering physiological concentration range.

Quick detection: The detection time for a single sample is only 5 seconds, supporting high-throughput screening.

Multi wavelength detection: Fixed or adjustable wavelength to meet the requirements of nucleic acid purity analysis and protein quantification.

　　Ultra trace nucleic acid analyzerThe principle:

Fluorescence detection: By binding fluorescent dyes to nucleic acids, specific wavelength fluorescence signals are excited, and the intensity is proportional to the concentration of nucleic acids.

Spectral absorption detection: Using the characteristic absorption peaks of nucleic acid at 260nm and protein at 280nm, the concentration is calculated by measuring the absorbance.

As an ultra trace high-performance full wavelength spectrophotometer, the ultra trace nucleic acid analyzer can quickly and quantitatively detect trace nucleic acids, proteins, bacterial cultures, etc. The sample detection concentration range is wide, the operation is simple, and it is widely applicable to disease control and quarantine institutions, biological products, and scientific research institutions.

Daily maintenance:

Cleaning: After testing, wipe the sample cell with anhydrous ethanol to avoid residual contamination.

Calibration: Calibrate the instrument with standard samples every month to ensure data accuracy.

Dustproof: Cover with a dust cover when not in use to prevent dust from entering the optical system.
