Analytical Services

SEAFDEC/AQD offers electron microscopy imaging (TEM and SEM), chemical, and microbiological analyses of the following:

  • feeds, feed ingredients, experimental animals and others (proximate analysis, fatty acid profile)
  • water (pH, alkalinity, chlorophyll, dissolved oxygen, nitrogen (ammonia, nitrate and nitrite), phosphate, total hardness, total suspended solids)
  • soil (pH, organic matter, available iron / phosphorus / sulfur)
  • food products and water (standard aerobic plate count or total viable count; coliform count, determination of Salmonella / Shigella / Staphylococcus aureus / Escherichia coli; yeast / mold count; water potability)

To request analytical services from SEAFDEC/AQD:

  1. Contact the laboratory by sending an email to for the availability of schedule, proper sampling procedure and packing of samples for analysis.
  2. Download REQUEST FORM.
  3. To pay, use the same payment options as the training / publications section of this website. Fill up the request form, attach proof of payment, and send separately from your sample.

    Fax to: (63-33) 330-7011
