The Spectrum Two is suitable for a wide range of applications and can be configured to your needs regarding the level of performance desired to meet the demands of your daily IR analyses. See the configurations table below for all available instrument options.

Spectrum Two FT-IR spectrometers feature:

  • Standard, high-performance, room-temperature LiTaO3 (lithium tantalate) MIR detector with a SNR of 9,300:1
  • Optional temperature-stabilized, high-performance DTGS (deuterated triglycine sulfate) MIR detector with a SNR of 14,500:1. Ideal for low-light, high throughput applications
  • Standard optical system with KBr windows for data collection over a spectral range of 8,300 – 350 cm-1 at a best resolution of 0.5 cm-1
  • Optional ZnSe windows, for use in exceptionally humid environments for data collection over a spectral range of 6,000-550 cm-1
  • Standard AVC with optional APV/AVI configuration

Additional features that allow for consistent performance of this system include:

Application Note

Detecting Manuka Honey Adulteration Using Mid-Infrared Spectroscopy Webpage: Spectrum Two

Common adulterants found in Manuka honey include beet, corn and rice syrups. The differing photosynthetic pathways in the plants used to produce these adulterants generally means that different techniques are required to detect them. Mid-Infrared spectroscopy with Adulterant Screen technology, can provide rapid detection of all three adulterants without the need for solvents or time-consuming sample preparation

Determination of DBPC and DBP in Transformer Insulating Oil According to ASTM D2668 and IEC 60666

Transformer insulating oil is often exposed to high temperatures due to the high voltage electrical applications for which it is commonly used. As a result, insulating oil degrades over time, reducing its ability to act as an insulator and possibly leading to equipment failure. 2,6-di-tert-butyl-p-cresol (DBPC) and 2,6-di-tert-butyl phenol (DBP) are commonly used in transformer insulating oil as antioxidants. It is common practice for more antioxidant to be added if the level drops below 0.15%. As a result of this, regular testing of transformer oils is necessary to ensure optimum functionality of transformer units. Infrared spectroscopy provides a fast method wherein the quantity of antioxidant in a sample may be determined in less than 30 seconds while adhering to regulations set out by ASTM D2668 and IEC 60666.

This application note describes how the PerkinElmer Spectrum Two FT-IR spectrometer provides a fast, simple and cost-effective method for evaluating the levels of antioxidant in transformer insulating oil.

Determination of THC and CBD in Cannabis Flower

This work shows an on-site, rapid and low-cost technique for the accurate measurement of flower potency. FT-NIR spectroscopy provides rich information regarding the chemical composition of cannabis flower. When combined with chemometrics, the FT-NIR offers unparalleled speed and simplicity that cannot be matched by traditional techniques. PerkinElmer Spectrum Two NIR with the Near Infrared Reflectance Module (NIRM) is used to quantify total THC and total CBD in dried cannabis flower. The use of FT-NIR directly at the grow site would reduce overall research and development costs for cultivators.

Glycerol Adulteration with Diethylene Glycol

Glycerol (or glycerin) is a colorless, odorless liquid that is generally safe for human exposure and consumption. It has many uses in the food, pharmaceutical and personal care industries due to its range of versatile properties allowing it to act as a sweetener, lubricant and humectant. Unscrupulous suppliers may adulterate glycerol to increase their profits. Diethylene glycol (DEG), the most common adulterant, has a number of properties similar to glycerol and is roughly three times cheaper. However, ingestion of DEG is toxic and thousands of reported cases of DEG poisoning have resulted in illness and fatalities worldwide.

The current FDA safety limit for DEG in glycerol is 0.1 % by weight. This study shows that using mid-infrared spectroscopy can detect DEG at that level.

IR Spec Analysis of Plastic Pharmaceutical Packaging Materials to USP 661.1

Packaging is defined as a means of providing protection, identification, and containment of a product during storage and transport until it is consumed. The pharmaceutical packaging industry has an estimated value of $68.7 billion, and when it comes to their packaging quality, it is essential that suitable physical, chemicals and biological properties are upheld to ensure integrity of the product and to meet relevant standards.

The PerkinElmer Spectrum Two FT-IR Spectrometer with UATR accessory provides a fast and robust method for determination of pharmaceutical packaging material. Furthermore, when used in conjunction with the Spectrum 10TM Enhanced Security, packaging can be easily analyzed while fulfilling requirements of 21 CFR part 11 compliance.

Optimization of the Decarboxylation Reaction in Cannabis Extract

Most cannabis extraction processes, independent of solvent or instrument choice, undergo a decarboxylation step whereby the carboxylic acid functional group is removed from the cannabinoids. The PerkinElmer Spectrum Two with the UATR accessory allows for the simple and rapid determination of cannabinoid concentrations in cannabis extract. The FT-IR-ATR technique offers a real-time solution to decarboxylation reaction monitoring. The ability to monitor this reaction over time would enable manufacturers of cannabis extract to optimize extraction conditions and identify process deviations. The FT-IR-ATR technique requires small sample quantities, zero sample preparation and minimal operator training.

Customer Story: North West 200 Motorcycle Road Race- Fast and Accurate Fuel Testing at the Race

The International North West 200 motorcycle road race is Ireland’s largest outdoor sporting event where skill and performance are pushed to the limits. To keep the focus on the riders and the bikes, the North West 200 requires each team to use a race-supplied control fuel. Determination of each team’s fuel compliance must be as fast and accurate as the race itself – so the outcome can be confirmed in real-time.

When it comes to testing, race organizers depend on highly accurate results within 10 minutes of sample collection. With that goal in mind, Euro M-Sport conducted exhaustive research on the available analytical options and instrumentation that would meet the specifications of the NW 200 fuel testing requirements.

    Data Integrity – Spectrum 10 Enhanced Security (ES) Software for Infrared Spectroscopy

    The FDA defines data integrity as “completeness, consistency, and accuracy of data. Complete, consistent, and accurate data should be attributable, legible, contemporaneously recorded, original or a true copy, and accurate (ALCOA)”. ALCOA itself has evolved to ALCOA Plus, which incorporates two of the fundamental definition terms as stated by the FDA; complete, consistent, enduring, and available. Compliance with 21 CFR Part 11 is mandatory for pharmaceutical companies and their suppliers to sell products into the United States, and also applies to other related industries.

    PerkinElmer’s Spectrum™ 10 Enhanced Security (ES) software platform for infrared spectroscopy provides structural requirements and features to assist with the needs for ensuring data integrity and compliance. It affords the system owner the ability to comply with regulations and incorporate features into the validation plan to exhibit compliance. The purpose of this document is to demonstrate how Spectrum 10 ES meets the technical requirements for 21 CFR Part 11.
