Analytical Instrumentation Boost sensitivity of metal-sensitive compounds
with newly extended off ering of inert LC columns Restek’s inert LC column line has been expanded to now include Raptor C18 and Force C18 columns. Ideal for analysing metal-sensitive columns, inert columns increase analyte response and sensitivity by reducing the nonspecifi c binding of chelating compounds. Combined with Restek’s selective stationary phases, these new inert LC columns are ideal for the analysis of metal-sensitive compounds, such as mycotoxins, pesticides, and methylmalonic acid.
Restek’s inert LC columns can improve peak shape without passivation or mobile phase additives, they also deliver increased response and analyte recovery, allowing lower detection limits. These columns will provide high accuracy and throughput with less variability, with less time-consuming conditioning and complicated passivation required. Restek’s inert LC column technology is available in various column types with more phases coming soon to accommodate a wide range of applications and testing methodologies: Raptor Biphenyl, Raptor C18, Raptor ARC-18, Force Biphenyl, and Force C18. These new columns help bring the benefi ts of inert technology to labs specializing in small molecule LC-MS/MS workfl ows.

The C Series chemical resistant diaphragm pumps from Wiggens are an excellent solution for continuous, oil-free pumping of corrosive gases and vapours and meet demanding applications. The multi-stage construction provides an advantageous combination of high pumping speed and ultimate low vacuum. All major parts in contact with pumped media are made of PTFE which are ideal for extremely aggressive/corrosive gases and vapours. The sealing system provides reduced leakage rates for improved ultimate vacuum (1mbar).
Wiggens is continuously expanding the line of diaphragm pumps and applying new technologies to the C Series. The latest models feature more powerful motor-driven multi-stage pump heads, making them an excellent choice for applications requiring high vacuum levels with corrosive gases and vapours. These pumps fi nd applications in pilot reactors, industrial rotary evaporators, the semiconductor industry, drying ovens, and various laboratory applications. The maximum pumping speed can reach up to 145L/min.
Equipped with a frequency conversion motor, these powerful pumps can achieve high vacuum levels quickly and with good stability, making them suitable for larger laboratory applications.
Furthermore, the frequency conversion vacuum pump helps reduce noise in the laboratory and extends the service life. If you have any questions about vacuum requirements for your experiments, please contact Wiggens for assistance.

Myron L® The 6PFCE
Company Ultrameter II 6PFCE features a comprehensive suite of in-situ water quality analysis tools
designed to replace more costly and less convenient laboratory equipment. A true one-handed instrument, the 6PFCE
delivers Conductivity, Resistivity, TDS,
pH, ORP, Free Chlorine Equivalent (FCE™), and Temperature readings quickly and easily with the press of a button.
Unlike other similar meters, 6PFCE Conductivity and TDS functions allow you
to select the solution type used to model the solution under test: KCl; NaCl; Myron L’s own 442 Natural Water™ Standard; or USER, programmable by you to model a known solution. The result is benchtop accuracy of ±1% of reading in a handheld instrument. Accuracy increases to ±.1% of reading at calibration point. Temperature compensation is automatic to 25°C or can be disabled by the user as required. Autoranging capabilities provide increased reading resolution across a broad range of applications.
pH readings are also temperature compensated, and you can choose to perform a 1-, 2-, or 3-point calibration depending on the range of samples measured to achieve ±.01pH accuracy. The pH sensor is of a proprietary construction and includes a large potassium chloride solution reservoir for long life. Myron L pH sensors are also user replaceable.
ORP readings utilize a 99.9% pure platinum electrode and a reference junction that is shared with the pH sensor. 6PFCE
reading accuracy is ±1 millivolt. In addition, the 6PFCE
ORP features a groundbreaking new way to determine Free Available Chlorine based on a predictive ORP
value. Empirical readings of the chemical activity of a solution are made without the hassle and subjectivity of colorimetric and test-strip methods.
Calibration and maintenance are simple, so the 6PFCE can be serviced by the user. The 6PFCE is also IP67 dust-tight and waterproof,
NEMA 6 submersible, and buoyant. Plus, Myron L service and technical support are included for the life of the product. More information online:
