Starch Thermal Stability Determination

Thermogravimetric Analysis (TG or TGA) refers to a thermal analysis technology that measures the relationship between the mass and temperature changes of the sample to be tested under program-controlled temperature. It is used to study the thermal stability and composition of materials. TGA is a commonly used testing method in R&D and quality control. Thermogravimetric analysis is often used in conjunction with other analysis methods in actual material analysis to conduct comprehensive thermal analysis and comprehensively and accurately analyze materials. The thermogravimetric analysis we often refer to is differential thermogravimetry analysis. differential thermogravimetry analysis is also called derivative thermogravimetry (DTG). It is the first derivative of the TG curve with respect to temperature (or time). The DTG curve is obtained by plotting the mass change rate of the substance (dm/dt) against the temperature T (or time t).

Sample Submission Guidelines

1.Sample Types

 

Starch samples, clients can provide the original sample for starch extraction by our company, which is subject to a separate charge.

 

2.Biological Replicates

 

A minimum of three biological replicates is recommended for robust results.

 

3.Quantity Requirements

 

Raw sample > 50 g; Starch >1 g.

 

4.Sample Preparation

 

1)Establish both control and experimental groups, ensuring a minimum of three biological replicates.

2)Ensure maintain consistency in timing whenever possible.

3)Minimize preprocessing; we prefer to handle these steps. Clients should ensure liquid samples are securely packaged in non-glass containers and buffered against shock and impact. Dry solid samples can be untreated or preliminarily ground. Fresh solid samples require no treatment when shipped with ice packs at ambient temperature.

4)When shipping with dry ice, samples should be cut into small pieces, each less than 1 cm³.

 

5.Packing and Shipping

 

1)Store samples in clearly labeled tubes, label with sample name, concentration, and preparation date. Ensure tube tops are sealed.

2)For transport, secure sample tubes in 50ml capped centrifuge tubes placed in sealable bags. Use dry ice or ice packs for transportation, avoiding repeated freeze-thaw cycles. DO NOT send the samples out on Fridays, to avoid weekend delays.

 

6.Labeling Requirements

 

1)Employ double labeling, ensuring clear identification on both the sample tubes and external packaging.

2)To prevent confusion, avoid simplistic labels like A/B/C or 1/2/3. Instead, use a combination of letters and numbers for unique sample identification, reducing the risk of duplication.

 

7.Additional Information

 

A minimum of 24 analyses is required. If fewer than 24 analyses are conducted, the cost will be calculated as if 24 analyses were performed.
