Our quality testing primarily encompasses two main areas: physicochemical sample pretreatment and microbiological analysis, supported by strict environmental controls and personnel protection measures.
Physicochemical Pretreatment (Ashing): Samples undergo high-temperature calcination in a muffle furnace to remove organic matter. Purpose: To determine total ash content or prepare samples for heavy metal analysis.
Microbiological Inoculation: Samples are diluted and inoculated onto culture dishes within a laminar flow clean bench to prevent contamination by unwanted microorganisms.
Microbiological Incubation and Sterilization: Inoculated samples are incubated in a thermostatic incubator for subsequent colony counting; a drying oven is used for the sterilization or drying of equipment.
Key Testing Parameters: Total ash content; microbiological indicators such as total bacterial count and coliform count.
