AST101 COD Microwave Digester

AST101 COD Microwave Digester Features:
1. Short digestion time, suitable for water samples.
2. Time-saving, cost-effective, and easy to operate.
3. Can digest multiple substances: Chemical Oxygen Demand (CODcr), Total Phosphorus (TP), and Total Nitrogen (TN).
4. Sealed digestion with overpressure protection.
5. Safe and reliable, with an audible alert upon digestion completion.
6. Can determine low CODcr values below 10 mg/L.
7. Can rapidly determine Chemical Oxygen Demand (COD) with heating; the data obtained corresponds to that obtained using classical methods.

AST101 COD Microwave Digester Product Introduction
1. Digestion Range: CODcr: 5-2500 mg/L, TP: 0.01-0.6 mg/L, TN: 0.05-4 mg/L
2. Digestion Time: 5-16 min
3. CODcr Resistance to Chloride Ion Interference: ≤10000 mg/L
4. Precision: When CODcr values are between 80-150 mg/L: Intra-laboratory relative standard deviation ≤ 4.3%, Inter-laboratory relative standard deviation ≤5.0%. TP and TN meet the requirements of the national standard (GB11889-11915-89) Water Quality Vocabulary (Parts 3-7) and Analytical Methods.
5. Accuracy: The correlation coefficient r > 0.999 for CODcr compared to the classical reflux method; the correlation coefficient r > 0.999 for TP and TN compared to the standard method.
6. When used for CODcr digestion: It has resistance to chloride ion interference and can determine water samples with CODcr values greater than 50 mg/L and chloride ion content as high as 10000 mg/L.
7. Number of samples to be digested (per batch): Standard configuration 6 samples, maximum up to 12 samples (customizable)
8. Microwave operating frequency: 2450MHz
9. Rated input power: 1300W (maximum)
10. Microwave output power: 800W
11. Dimensions: 457mm×395mm×271mm
12. Applicable environmental conditions:
A: Ambient temperature: 5—40℃
B: Ambient humidity: ≤90%RH
C: Atmospheric pressure range: 86Kpa—106Kpa
13. Operating conditions:
1) The instrument should operate on an AC (220±22)V (50±1)Hz power supply.
2) Operating mode: Continuous.
