How to use Search System for Mixture Standard Solutions of Pesticides / Veterinary-drugs

Search System for Mixture Standard Solutions of Pesticides / Veterinary-drugs is a function to execute an easy search through more than 200 mixture standard solutions for pesticides and veterinary drugs by FUJIFILM Wako based on the intended analyte. This article explains from the outline of the search function to how to use it.

Benefits of using a mixture standard solution

Pesticides and veterinary drugs are essential materials in order to maintain the yield and quality of agricultural products and livestock products, and reduce the burden on the workers.

While pesticides and veterinary drugs that remain in food and tap water are mainly analyzed using the simultaneous analysis method which employs HPLC and GC, it is quite difficult to obtain all the analytical standards for the analytes that need to be measured and prepare them accurately for the multicomponent simultaneous analysis method. Conducting simultaneous analysis becomes much easier by using the mixture standard solution, which already contains the mixture of analytes to be analyzed with guaranteed concentration values.

Benefits of Search System for Mixture Standard Solutions of Pesticides / Veterinary-drugs

At present, FUJIFILM Wako sells more than 200 mixture standard solutions for pesticides and veterinary drugs. In the past, it was necessary to compare the analytes contained in the mixture standard solutions and the analytes one wished to measure by the catalog or website when looking for the appropriate mixture standard solution.

Search System for Mixture Standard Solutions of Pesticides / Veterinary-drugs, which has been newly released, is a function that allows you to search the mixture standard solutions by specifying the pesticides and veterinary drugs you want to analyze. It also allows them to find the products with higher degrees of match, as the search results are displayed in the order of those containing the largest number of specified analytes.

In addition, the search results include the columns that were used in product tests at FUJIFILM Wako, which can be used as reference information for examination of analytical conditions after the purchase of products.

Hou to use

How to use Search System for Mixture Standard Solutions of Pesticides / Veterinary-drugs is provided below while taking the simultaneous test method described in Annex Method 18, complementary items to set the targets for water quality management of the Japanese Water Supply Law as an example.

Pesticides listed on Annex Method 18, complementary items to set the targets for water quality management of the Japanese Water Supply Law*

Asulam Carpropamid Methomyl 2,4-PA (2,4-D)
Azoxystrobin DCMU (Diuron) MPP (Fenthion) Probenazole
Bensulfuron-methyl Dymron MPP Oxon Siduron
Bensulide (SAP) Fipronil MPP Oxon Sulfone Thiodicarb
Bentazone Flazasulfuron MPP Oxon Sulfoxide Thiuram
Carbaryl (NAC) Halosulfuron-methyl MPP Sulfone Triclopyr
Carbendazim (MBC) Iprodione MPP Sulfoxide Tricyclazole
Carbofuran MCPP (Mecoprop) Oxine-copper (organic copper)

(): Other Names
In blue cells: Pesticides that require extemporaneous preparation in Annex Method 18

▼Register the search keywords

wb034699_img01.png

The candidate keywords that can be specified will be displayed by entering a partial analyte name or CAS RN® into the search window. When the applicable pesticide or veterinary drug is selected from the list, the analyte is registered in the "Keywords". Since other names of analyte and CAS RN® for salts are also registered as keyword candidates, we recommend that you enter multiple keywords if you cannot find the intended analyte.

You can also register the intended analytes collectively from the list of analytes displayed in "Search from Analyte List".

▼Look for the products from the search results

The search screen displays the results in order of higher match to the registered keywords. Since the registered keywords are highlighted, it is also possible to combine the mixture standard solutions depending on the intended analytes from the search results.

Based on these search results, a single analytical standard needs to be prepared for Carbaryl, as it is not included in the mixture standard solutions of FUJIFILM Wako due to the issue of stability, while the 28 Pesticides Mixture Standard Solution WQ-3 seems to be most suitable. Since the single analytical standards of the registered analytes are displayed at the end of the search results, it is possible to select the single analytical standard that is not included in the mixture standard solution from there.
