Responding to RoHS2.0, 4 new phthalate screening solutions

On June 4, 2015, the Official Journal of the European Union (OJ) issued the RoHS2.0 Amendment Directive (EU) 2015/863, which included the original RoHS 6 substances (lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers) On the basis of this, 4 phthalates were added to the RoHS2.0 restricted substance list. So far, RoHS2.0 has 10 controlled substances.

According to RoHS2.0 testing standards, manufacturers need to purchase relevant equipment for rapid raw material screening, material self-inspection, internal quality control, customer factory audits, etc. (instruments required for conventional configuration: GCMS+EDXRF spectrometer), but purchase these equipment With millions of dollars at every turn, many companies feel tremendous pressure, and companies have to do raw material screening. If they do not do screening, product production will bury huge hidden dangers, and companies cannot control whether their products meet standards. Based on the importance of internal screening and the huge investment required to purchase equipment, Jingu Keyi has developed a set of new solutions specifically for the rapid screening needs of the four phthalates in Rohs2.0: TP30-GC Micro-lysis desorption o-benzene rapid screening solution

This TP2-GC system can detect 20 kinds of o-benzenes and meet the needs of o-benzene detection. In addition to o-benzene, this system can also be used as red phosphorus flame retardants, organic solvent residues, polymer materials, and volatilization in materials. Sexual organics, etc., powerful!

Part 1: Introduction of TP30-GC ROHS2.0 Ortho-Benzene Solution

The TP30-GC program has the following advantages:

1. Short sample-making time : 20 minutes/sample-making time fully meets the needs of enterprise users for rapid screening;

2. No waste gas or waste liquid: This kind of waste gas does not require reagents, pre-treatment, and no waste gas or waste liquid;

3. Low purchase cost: PY+GCMS purchase cost 1.5 million, TP30-GC purchase cost less than 350,000;

4. Low cost of use: no pre-treatment, no reagents and consumables are required, and the cost of use is less than 3,000 yuan a year;

5. Direct sampling, simple operation: direct solid or liquid sampling, five operations produce results, and production line workers can operate;

6. Built-in standard curve: more intuitively judge whether the material exceeds the standard of o-benzene (exclusive technology);

7. Suitable for 100% polymer materials: chemical methods are only suitable for 70% materials, TP30-GC is suitable for 100% materials

8. No need for a professional laboratory environment : it can be installed and used only in an ordinary operating space with air-conditioning power supply.

Results and discussion:

Standard curve and linear range (detection limit)

Configure the DIBP standard solutions with concentrations of 50ppm, 100ppm, 250ppm, 500ppm and 1000ppm, and draw the standard curve with the concentration as the abscissa and the quantitative component peak area as the ordinate. The standard curve and linear correlation coefficient are shown below.

The following table is a comparison chart of peak height and peak area of 5 different concentration standards:

Concentration (ppm)	Peak height (pA)	Peak area (A)
50	2,038.7	8,472.5
100	2,289.6	12607.7
250	5720.6	24674.0
500	1,2090.8	53037.4
1000	24747.2	120759.3

The lowest detection limit of each component calculated by 3 times the signal-to-noise ratio is 25ppm
