What is Solubility?

Solubility is defined as a chemical property referring to the ability of a given substance, the solute, to dissolve into a solvent. It is measured in terms of the maximum amount of solute dissolved in a solvent at equilibrium. The resulting solution is called a saturated solution.

SPEX talks about Terpenes!

8790db63-4afa-478f-b799-30599d8c2b61

Cannabinoids and pesticides are normally the main focus of native and foreign chemical constituents found in cannabis. However, terpenes deserve their fair-share of the spotlight. Terpenes and their related terpenoids are the primary compounds in most botanicals and essential oils. Many consumer products rely on terpenes for their character, flavor and fragrances, making them ideal for foods and aromatherapy alike. For example, Myrcene, beta-Pinene, beta-Caryophyllene and alpha-Humulene are found in hops and important to the flavor and aroma of beer. Damascene and Geraniol provide the floral notes of wine grapes and roses.

Terpenes are of interest for both recreational and medical cannabis fields. Researchers are able to characterize different cannabis strains based on their terpene profiles. Terpene profiles allow recreational users to identify which flavors and fragrances they prefer. More importantly, research recognizes terpenes also have therapeutic benefits. For example, beta-Myrcene and Nerolidol are mild sedatives and Limonene an anti-inflammatory, each providing key therapeutic benefits. Some research also suggests terpenes work synergistically with themselves and other native compounds to enhance therapeutic effects, similar to the cannabinoid “Entourage Effect”.

As the industry evolves, the need for more accurate and precise analytical methods and standards will continue to grow. SPEX CertiPrep is proud to be at the forefront of the industry, continuously adapting our standards to comply with changing regulations and increasing consumer demand for safer products.

Premixed Pesticide Multi-Compound CRMs

Chemical pesticides have become an integral part of the agricultural toolbox, offering protection to crops from destructive pests. However, an unfortunate side effect of their uses is the potential leaching of these, oftentimes, harmful chemicals into the environment leading to their eventual presence in the human food chain. As a result, pesticide residue analysis has become a critical testing process for many different types of laboratories.

Unfortunately, pesticide residue testing is a long, expensive, and complicated process, covering hundreds of different compounds. Fortunately, as the leader in HPLC, GC, LC/MS, and GC/MS pesticide CRMs, SPEX CertiPrep is happy to assist our customers with all of your pesticide CRM needs.

For your convenience, we have designed a pesticide residue testing kit which includes 144 of the most commonly analyzed pesticides per EPA, AOAC, FDA and other international testing methods. The kit is structured to maximize stability and solubility, while minimizing unwanted analyte interaction and interference; enjoy shorter calibration times, fewer injections and money savings, as compared to purchasing individual pesticide standards.

Introducing Carbon Black Reagents for ASTM D1510

Details Matter…

Our sodium thiosulfate solutions are prepared from ACS Grade, micro-crystalline Na2S2O3. In order to maximize shelf life, our matrix is prepared using double-deionized, ASTM Type 1 Water.

Our iodine solutions are prepared from ACS Grade potassium iodide and crystalline elemental iodine. To guarantee a clean and stable product, our matrix is prepared using double-deionized, ASTM Type I Water.

All solutions are prepared gravimetrically, using high accuracy analytical balances, to ensure precise target concentrations. Each batch is thoroughly homogenized using a high speed industrial mixer to ensure reliable results from the first bottle to the last.

We are titrating our samples on our automated titrator. The automated dosing drive uses 10,000 steps over it 20 mL volume, so its dosing increment can be as small as 2 μL. For these applications, we are using a minimum dose of 10 μL for the sodium thiosulfate endpoint and 4 μL for the iodine endpoint. These settings achieve the extremely precise measurements for each titration while also staying within the parameters of the dosing unit.

As stated on our Certificate of Analysis, the sodium thiosulfate is run against a 0.1 N potassium dichromate solution. The exact normality of this solution is calculated by comparing it to NIST potassium dichromate. A set of 6 samples are run that must all be within the nominal value of 0.0394 N ± 0.00008 N.

Then the certified sodium thiosulfate is used to titrate iodine. A set of 3 samples are run that must all be within the nominal value of 0.0473 N ± 0.00003 N.

Before releasing either of these reagents for packaging, we run QC checks with a previous lot to ensure accuracy over time.
