New Pesticide Product Line Wednesday, February 10, 2010
Today, ULTRA is launching a new pesticide standards program. After extensive analysis of the data generated from its existing pesticide program and evaluation of the new food and environmental safety regulations in the national and international community, ULTRA has identified more than 400 of the most commonly requested pesticide/solvent combinations.
The new program offers all these solutions on the shelf, packaged in convenient 1.2 mL volumes in flame sealed ampoules. They are fully validated and available for immediate shipping. The pricing will remain at catalogue pricing levels, thereby avoiding costs normally associated with custom formulations. Most importantly, the solutions are instrument-ready in the solvent most appropriate for the intended analysis, whether by GC/MS or LC/MS. The solvent is also the most compatible with the compound, in order to maximize the stability and expiration. Please note that pesticides in alternate solvents, volumes or concentrations not included in the new program can still be obtained through ULTRA Scientific’s extensive custom library.
ULTRA’s program comes at a time when protocols utilizing the QuEChERS rapid pesticide analysis technique, AOAC 2007.01 and EN15662, are requiring an unprecedented flexibility in calibration solution design. ULTRA’s solutions are designed to provide the analyst with the flexibility to prepare mixes most suitable for the analysis they need to do today. Whether it is the QuEChERS analysis of peaches or grapes by AOAC 2007.01 or cabbage and endive by EN15662, the analyst is now sure to have the correct pesticide readily available for their particular analytical need.
Pesticides are employed for many reasons. The most common reason is to protect food crops from being damaged or destroyed by insects, fungi, or other harmful pests thereby insuring maximum kilogram per hectare output. Other uses of pesticides include protecting human dwellings from infestations of pests that may destroy the structure or harm the inhabitants, preventing pests from harming livestock, and clearing land and waterways of unwanted vegetation to name just a few.
Pesticides are categorized by the tasks they perform and the chemical grouping they fall within. Classical task categories are insecticides, acaricides, nematocides, fungicides, bactericides, rodentacides, defoliants, etc. Classical chemical groups include the organochlorines, organophosphates, pyrethroids, ureas, triazines, organometallics and metallics and the list goes on. While some pesticides are naturally occurring, the vast majority are synthetic, with most of the synthetic pesticides being created within the last 100 years.
Pesticides have been tremendously useful in insuring the productivity of the agricultural system, allowing more tonnage per hectare output than could be expected without their use. Likewise many pests harmful to humans have been controlled through the use of pesticides, helping to dramatically reduce and in some cases eradicate diseases transmitted by these pests. The use of pesticides has been integral to human population growth and prosperity.
Along with the benefits, however, pesticides have been shown to be damaging to the environment as well as harmful to humans. Pesticide overuse causes insects and other pests to become tolerant to the point of being immune to the chemical, thereby reducing their usefulness. As pesticides move through the environment they impact non-target organisms causing unpredictable effects such as the disruption of hormone systems, or mutagenic effects. Pesticide residues have been detected in every ecosystem found on earth, regardless of whether they have been applied directly to that ecosystem or not.
Historically, the analysis of pesticides in the environment has been limited to the organochlorines, organophosphates and triazines as these have been the most problematic due to their persistence and/ or their toxicity. Other chemicals, developed more recently, have been studied less due to the belief that they degrade quickly and/or have a lower overall impact to the environment. Now, however, there is a growing global awareness that any pesticide, in the wrong place, may prove detrimental in the long-term to human and environmental health. This awareness is now driving a strong international regulatory effort to monitor all pesticides, specifically on food stuffs, to insure that human consumption of pesticides is minimized.
ULTRA Scientific has been a leader in the manufacture of pesticide calibration solutions since 1976. During its tenure, ULTRA has provided pesticides in several different container, solvent and volume combinations: initially, as pure, neat materials and as mixtures containing the common, regulated pesticides; later, as solutions containing single pesticide components. As new compounds have come into use in the field and have become of interest to the environmental research and lab industry, ULTRA has added them to its ever expanding inventory.
In 2005, ULTRA launched a line of custom pesticide solutions. The program allowed the client to pick the pesticide of interest in one of two concentrations from ULTRA’s ever increasing inventory, choose the solvent and volume and choose the container. By providing the client with the product they need, at a competitive price, ULTRA demonstrated its commitment to its clients. While this program has been a tremendous success, ULTRA has witnessed an overall standardization in solvent and container selection. Now, five years later, the time has come to take the pesticide program to new heights.
