Product safety laboratory needed for OECD skin corrosion and irritation testing by in vitro methods OECD TG431, TG430, TG435, ...Apart from liquid product, also solid products should be tested. By experience, we know that the absorptive properties of silica-based carriers reduce the corrosivity of the liquid mixtures that are absorbed. However, this aspect is annihilated by adding water to the solid to facilitate the test procedure. Are there procedures available to test for corrosivity without requirement for added water?

Large chemical company needed analytical chemistry laboratory for identification of sulfur species in liquid samples. Analysis of our sample by XRF shows the presence of sulfur but our GC instruments don't detect any sulfur. We use a GC equipped with a PFPD and a non-polar capillary column. We have also used a GC with FPD and non-polar capillary column. We suspect the sulfur that is present is non-detectable by GC (or at least not by our system).

Skincare company needs dermatology clinical research laboratory for development of a protective cream for prolonged work in gloves that helps avoid excessive sweating on the skin of hands, restrains the growth of harmful microorganisms (bacteriostatic effect), and improves microcirculation in the vessels of the skin of hands, protects cells from harmful factors. This product has 3 main properties, which need to be confirmed: 1) Antiperspirant effect 2) Improvement of cutaneous respiration 3) Bacteriostatic effect We are planning to register this product as a cosmetic product. So we have to confirm these claims with test reports by 1) Antiperspirant effect was confirmed by gravimetric method and method the probe of Minor (iodine-starch test). The effect of the product was shown to be lasting up to 4 hours. 2) Skin respiration (cutaneous respiration) is the property, which includes all kinds of exchange processes in the skin (supplying the skin with oxygen), metabolic processes (synthesis of collagen and elastin), regeneration processes and improving the viability of the skin cells when exposed to harmful environmental factors. These properties are provided by the 2 components of product (caffeine and ginger extract) increasing ATP synthesis in the cell (under the influence of acetylglutamine), as well as the microcirculation in the skin. The effect of product to improve cutaneous respiration was confirmed by laser Doppler flowmetry. 3) Bacteriostatic effect the temporary suppression of the ability of microorganisms to reproduce (not the same as antibacterial action!). This effect is side-effect, because the composition of the product contains no antibacterial ingredients. The effect is achieved by the common action of the antiperspirant complex.

Construction laboratory needed for weld failure analysis and root cause analysis of seam failures of Air Supported Structure buildings that are produced using Radio Frequency welding.
A brief background of the situation is this: We use architectural coated fabric for the exterior of the building, typically 30 mil thick, or 28 oz per square yard. The building is designed with a thermal liner of laminated PVC to create a dead-air space between layers for insulation. The thermal liner is 15 oz per square yard. Often a third layer is used to create two dead-air spaces similar to a triple pane window. All layers are welded simultaneously, so in the case of Triple Wall construction there are 6 layers of material being RF welded.
The failures we have experienced occur between the two exterior fabrics, usually during the hottest weather conditions. The weld will open up and appears that the two exterior layers were never fully welded. However, destructive shop tests show that the welds were fully welded.
.My research includes possible tests as final weld thickness, current monitoring, weld temperature monitoring, and others.
