CHROMABOND SiOH

Macherey-Nagel GmbH & Co. KG (15188)

CHROMABOND® SiOH
Unmodified silica phase for SPE

Unmodified, weakly acidic silica, pore size 60?, particle size 45µm, specific surface 500m²/g, pH stability 2 to 8, very polar, adsorbs humidity from air, for this reason it should be kept well closed and if necessary dried before use due to its high affinity for polar compounds it should not be conditioned with polar (e.g. methanol) or water-containing solvents.

Recommended applications: aflatoxins, chloramphenicol, pesticides, steroids, vitamins.

LLG (9693)

Extraction kits Copure® QuEChERS
Extraction and clean-up mixtures for sample preparation in the pesticide analysis of vegetable foodstuffs according to EN 15662 using GC/MS or LC/MS after acetonitrile extraction and purification using the dispersive SPE-QuEChERS method.

The samples are first extracted with Mix A. Purification is done with one of the following mixtures:
-Mix B (Clean-up mixture for fruits and vegetables with low fat content, e.g. apples, strawberries)
-Mix C (Clean-up mixture for fruits and vegetables with high fat content, containing oil/wax, e.g. avocados)
-Mix D (Clean-up mixture for moderately chlorophyll/carotenoid-containing fruits and vegetables, e.g. carrots, salad)
-Mix E (Clean-up mixture for fruits and vegetables with high chlorophyll/carotenoid content, e.g. sweet peppers, spinach)

If required, add ceramic homogenising beads for better mixing.
-Mix A contains a bag with the required amount of mixture and a 50 ml empty tube
-Mix B, C, D and E are pre-weighed into a 15 ml tube

CHROMABOND QuEChERS extraction buffer mixes / clean-up mixes

Macherey-Nagel GmbH & Co. KG (15205)

CHROMABOND® QuEChERS extraction buffer mixes / clean-up mixes
QuEChERS method and pre-mixes
Within a few years after its devleopment by Anastassiades et al. the QuEChERS method has gained a leading position for determination of pesticide residues in food by GC-MS or LC-MS allowing rapid and cheap clean-up of strong matrix-contaminated samples.
Standard clean-up of food samples
10 g sample are homogenised with 10 ml acetonitrile. After adding the internal standard the sample is shaken with 4 g MgSO4 and 1 g NaCI and afterwards centrifuged. 1 ml of the supernantant is spiked with 25 mg CHROMABOND® Diamino and 150 mg MgSO4 and shaken again. After centrifugation the supernatant is injected into the GC/MS.
Extraction mixtures for sample preparation for determination of pesticides in food samples.

MACHEREY-NAGEL offers a number of individually weighed and pre-mixed buffers and extraction mixtures, specially composed for different sample matrices.
Mix I and Mix II are extraction mixtures, Mix III to Mix VI are clean-up mixtures.

The food samples will be extracted with either Mix I or Mix II.
Afterwards they will be purified with one of the following mixtures:
-Mix III (samples with low fat content; e.g. apples, strawberries),
-Mix IV (moderate content of chlorophyll and carotinoids; e. g. carrots, lettuce),
-Mix V (high content of chlorophyll and carotinoids; e. g. bell peppers, spinach),
-Mix VI (high fat content; e. g. avocados).

Every mix is prepacked in a 15 ml centrifuge tube. Pack of 50 pieces.
