Determination of Common Counterions and Impurity Anions in Pharmaceuticals Using a Capillary HPIC System with Suppressed Conductivity and Charge Detection
Recently, identification and quantification of ions in early stage drug development has gained increasing attention, because the APIs maybe contaminated with different counter ions from synthesis steps, and because selecting the counter ion to enhance APIs’ solubility and stability is becoming a key step in formulation development. This presentation demonstrates the identification and quantification of 22 commonly found anions in pharmaceuticals in a single run using a high-pressure capillary IC system (HPIC) with 4-μm particle ion –exchange column, and CD-QD dual detectors.
Determination of Carbohydrates in Various Matrices by Capillary High-Performance Anion-Exchange Chromatography with Pulsed Amperometric Detection (HPAE-PAD)
This presentation describes the combined advantages of a reagent-free capillary format Ion Chromatography (IC) to determine monosaccharides and disaccharides in various applications, from low concentrations in synthetic urine samples to high concentrations in beverage samples. In a reagent-free IC system, the hydroxide eluent is electrolytically generated inline to deliver accurate and precise concentrations for isocratic or gradient separations by only adding deionized water. Eluent generation eliminates carbonate contamination and errors from manual preparation. A capillary scale system with µL/min flow rates can run 24/7, always on and always ready for samples.

U.S. EPA and many state agencies are investigating fracking in Marcellus Shale’s impact on environmental water quality. Public outcry has led to drafting legislation. Increased levels of bromide in drinking water systems correlate to higher levels of brominated disinfection byproducts. Trace metals (i.e., arsenic, selenium, lead), important constituents of flowback water, must be accurately determined for regulatory compliance, challenging due to high levels of dissolved salts which can cause physical and spectral interferences. Here, experts discuss monitoring and measuring anion concentrations in water from recycling impoundments, the typical constituents reported for Marcellus Shale fracking operations, flowback water preparation, and ICP-OES and ICP-MS metals analysis.
Analysis of Cations in Hydraulic Fracturing Flowback Water from the Marcellus Shale Using Ion Chromatography
This presentation describes the determination of cations in hydraulic fracturing flowback water using ion chromatography. In this work, sodium was most abundant, followed by calcium, strontium, magnesium, potassium, barium, ammonium, and then lithium, respectively. The quantity of scale-forming ions, such as calcium, strontium, and barium, is particularly informative because it can be used to determine the amount of anti-scaling agent in fracturing fluid mix that will maximize hydrocarbon recovery.

Initially U.S. EPA 300.1 (Ion Chromatography with conductivity detection) sufficed for bromate regulatory requirements. As bromate toxicity concerns increased, lower regulatory limits (and lower MDLs) were imposed, leading to use of EPA 317’s and 326’s postcolumn derivatization and visible detection methods, although they sacrifice robustness and ease of use. Simultaneously, enhancements in column chemistry improved the MDLs possible with EPA 300.1. And since it is still impossible to overcome matrix effects with certain drinking water samples, EPA 302’s 2-D IC method was approved to maintain testing ease-of-use and robustness. Here, experts detail the bromate analysis methods and necessary validation steps.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
