The plasticizer is a colorless and odorless liquid polymer material additive, it can effectively make the product flexibility and plasticity increase. The plasticizer is widely used in a wide range of application, many types. In biofertilizer and feed packaging, storage, and transportation are common in the process, and prone to migration of plasticizers. Migration and the amount of time are correlated, the longer the plasticizer residues in biofertilizer and feed products will be more.
Plasticizers have a variety of chronic toxicities, and some plasticizer components are carcinogenic, mutagenic, or reproductive toxic. Therefore, Lifeasible offers customers a variety of methods to detect multiple packaging contaminants in biofertilizers and feeds, including plasticizers, heavy metals, and organic volatiles.

We can use solid phase extraction enrichment, HPLC for detection, suitable for the simultaneous separation and detection of a variety of plasticizers. It has the advantages of high separation efficiency, high speed, wide range of mobile phase selectable, high sensitivity, and easy collection of effluent components.
In addition, the most commonly used GC-MS method has good repeatability, precision, and high accuracy. We can also use liquid-liquid microextraction combined with GC-MS to determine plasticizers' content in various biofertilizers and feed packages, and we can correlate the plasticizer content.
- Organic volatile testing case
For volatile organic pollutants, we use hexane as the extraction solvent for ultrasonic extraction of pollutants on biofertilizer and feed packaging materials, and after extraction, we concentrate them by rotary evaporation and finally characterize the concentrated pollutants by ionization using GC-MS analysis.
For heavy metal contamination, we can detect the contamination of heavy metals in the packaging and the contamination of heavy metals in raw materials. We use HG-AFS and ICP-OES methods, which can analyze multiple elements simultaneously. With the advantages of a wide dynamic linear range, high precision, good stability, and fast analysis, it can be applied to the detection of trace heavy metals.
Lifeasible offers testing services for a wide range of contaminants such as plasticizers in biofertilizer and feed packaging, which is an essential indicator for assuring and measuring product quality. Please contact our staff to learn how we can provide testing services for you, and samples can be arranged to be sent at any time.
