Typical citrus pesticides and polar pesticides in pomelo

P2722-RT covers the most relevant pesticides for the matrix pomelo.

The basic price of 350 € covers the overall organisation, the shipment (within the EU), as well as a share of the homogeneity testing.

The participants are free to choose between the modules

module 1: pesticides, covered by common pesticide multi-residue methods. A selection of the pesticides mentioned below are spiked.
module 2: chlorate, perchlorate, ethephon, glyphosate, maleic hydrazide, phosphonic acid.
module 3: matrine, oxymatrine.
module 4: morpholine, diethanolamine, triethanolamine.
module 5: difluoroacetic acid, trifluoroacetic acid.

Homogenates of pomelo, spiked and unspiked, are provided as test material and blank material.

The analytical data are assessed with respect to

the correct identification of the multi-method pesticides,
the comparability (z-score), and
the trueness (70 to 120% of the spiked level, as far as applicable).
