“…The use of other solvents, such as ethyl acetate or acetone as extractants, has been tested (Lehotay et al 2010;Cunha et al 2007), but MeCN still remains as the priority solvent for the 4 QuEChERS procedure. The combination of MeCN as extractant combined with PTV injection has allowed reaching low limits of determination when combined with fast GC techniques (Hada et al 2000;Hercegová et al 2005;Korenková et al 2003).…”

Measurements of organophosphorus pesticides residues were conducted on four different baby food puree based on vegetable, fruit, white fish and veal, products based on cereals and biscuits packed in cardboard box using gas chromatography with thermoionic specified detector (GC-TSD). The lowest concentration of organophosphorus compounds was found for sulfotep, 0.00006 mg/kg in biscuits, while the highest concentrations were found for diazinon and fenchlorphos, with values of 0.1096 mg/kg and 0.1903 mg/kg, both in the grain samples.

“…The method of fast GC/MS for the pesticide residues analysis in apples was developed and validated (HERCEGOVÁ et al 2005). The sample preparation based on acetonitrile extraction and SPE-NH 2 cleaning was modified, combined with the cell disruption, and optimisation of several parameters in the whole sample preparation procedure was performed.…”

“…The changes in the peak response with a number of injections were also eliminated by injections in sequences, where after 3 injections of the blank matrix sample (in order to occupy the active sites in the liner and to stabilise the conditions of an inlet) the alternation of spiked samples and real samples (resp. matrix matched samples) follows (HERCEGOVÁ et al 2005). For the determination of the concentration levels of pesticide residues in real samples, the subsequent sequence was used: 3-5× blank matrix standard, 2 parallel real sample extracts, 1× matrix matched standard, 2 parallel real sample extracts, 1× matrix matched standard, 2 parallel real sample extracts, 1× matrix matched standard.…”

DÖMÖTÖROVÁ M., HERCEGOVÁ A., MATISOVÁ E. (2006):Monitoring of pesticide residues in apples from Slovakia for baby food production. Czech J. Food Sci., 24: 84-92.There is a basic lack of information about the presence of pesticide residues in apples obtained from farms in Slovakia collaborating with baby food producer. Residues of several pesticides (widely used for the protection on apple trees) have been determined in apples (a common raw material for the baby food production and baby food) from Slovakia (agricultural area in the South of Slovakia). The analysis of the pesticides was performed by gas chromatography on CP-Sil 5 CB (15 m long, 0.15 mm I.D., film thickness 0.15 µm) with normal bore retention gap (1 m long, 0.32 mm I.D.) using the subsequent determination with MS detector in SIM mode, after the acetonitrile extraction of the pesticide residues from apples, the clean-up and preconcentration steps of samples with SPE-NH 2 . For the study pesticides belonging to various groups were selected, such as organophosporus pesticides, oximinoacetates, anilinopyrimidines, triazoles, and triazines pyrethroids. The GC-MS analysis of pesticide residues in all samples searched showed that most of the detected and quantified residues were below 10 µg/kg which corresponds to the maximum residual limit for pesticide residues in baby food.
