Starch Particle Size Distribution Determination
The size of starch granules has a significant impact on the physical and chemical properties of starch, such as starch viscosity, swelling force, gelatinization temperature, etc. It also affects the degree of substitution of starch in the production of modified starch. The laser particle size analyzer uses laser as the light source. When the light encounters the particle sample, it is scattered at different angles. The scattered light is measured by a multi-element detector, and the values related to the scattering pattern are stored. Through optical models and mathematical analysis, this process yields qualitative results regarding the sample’s particle size distribution.

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.
