Calorific Value Determination in Liquid Food such as Baby Food_Hunan Sundy Science and Technology Co., Ltd-Sundy,Calorimeter,Proximate Analyzer,Elemental Analyzer

Standard
ASTM D5865, GB/T 213

Sample Preparation

sample weight is less than 0.3g
Accessories
Benzoic acid with specified calorific value
99.5% pure oxygen (Note electrolytic oxygen is not allowed to be used)

Capsule

Instrument : SDAC1200

Test Conditions

· Oxygen supply pressure: 3.0 MPa

· Oxygenation time: ≥15s

· Outer drum temperature: 28℃

· Inner tub temperature: 26℃

· Water tank temperature: 24℃

· Ambient temperature: 23℃

· Ambient humidity: 55%

Procedure

1. Test the capsule to get its own calorific value

2. Take one capsule and get its weight

3. Weigh the sample to 0.3g (Note : sample must be in the capsule ,and seal the capsule after weighing)

4. Add the additive benzoic acid (around 0.5g) to the weighed sample

5. Condition the instrument as below

a) Test a benzoic aced sample to check the instrument

6. After conditioning the instrument, load the sample to the bomb

Note :1. the ignition wire must touch the benzoic acid during loading the sample to the bomb;

2. For ASTIM D5865 standard, filling 1mL distilled water into the bomb ;
For GB/T 213 standard ,filling 10mL distilled water into the bomb

6. Charging the bomb with oxygen under 3MPa

7. Put the bomb into instrument, and input the sample weight on the software

8. Input the weight and calorific value of two kinds of additives

9. Click “Start” to analyze the sample or set" Auto start".
